STFC-RAL-CR03 R61: For inviting me here. So last time, 2025 years ago, so I was talking about similar stuff. But now there are new things here, so please interrupt me anytime you like this clarification. So it's already. So don't leave your questions immediate questions to them.
STFC-RAL-CR03 R61: So I'll discuss some selected selective topics on the dark matter
STFC-RAL-CR03 R61: stuff. And actually, well, document is popular. So and well, if you look at
STFC-RAL-CR03 R61: well, the trend is number of papers on that matter. My favorite graphs. So that matter is favorite. Well, and he support tends to be run down, and then, unfortunately, depending on your preference.
STFC-RAL-CR03 R61: X dimensions. And this is this is the technical or dynamic flow which is kind of up and down, but
STFC-RAL-CR03 R61: still our admin well, and that matter could be the kind most of the topics. And actually, that matter what unifies all the topics. And we can see a lot of publications.
STFC-RAL-CR03 R61: And we know that dark math is there.
STFC-RAL-CR03 R61: Question is what it is.
STFC-RAL-CR03 R61: So we know from Galactic Standard Galactic Relation Terms from Cnb. Peaks
STFC-RAL-CR03 R61: well with it, especially while there is a like. It's hard to see whether it's the acoustic peaks, which is very
STFC-RAL-CR03 R61: besides, to to understand how much amount of that matter we have.
STFC-RAL-CR03 R61: and which cannot essentially be mimicked by Mom, probably as well as they bought bullet cluster, which is another like Mom Killer. I would say
STFC-RAL-CR03 R61: gratational lensing and large scale structures established amount of that matter which is about like whatever 2324% of the budget universe.
STFC-RAL-CR03 R61: The only question is it? What is he? So
STFC-RAL-CR03 R61: we know that that matter interrupts gravitational and nothing else.
STFC-RAL-CR03 R61: We don't know speed we don't know mass. We know it's stable or not. On the scale, it might be stable with scale, but it still can be. The case still can have lifetime, maybe. Well.
STFC-RAL-CR03 R61: 100,000 times more than likely the universe, but well, with this case will be having between us. But we don't know.
STFC-RAL-CR03 R61: It can involve different couplings, new interactions, new gauge groups, and it can be thermal or no thermal.
STFC-RAL-CR03 R61: And so it could be a lot of surprises. That's the point. I mean, we don't know what it is, and it could be some coming
STFC-RAL-CR03 R61: any well, not any minute, but a a well, it could be around the corner. So so
STFC-RAL-CR03 R61: the point is that here I wanted to discuss how to decode that method. We don't have a signal, what we can decode. But we need to prepare ourselves. That's the point. So the moment we can make a classification of that Meta model, make classification of the signatures, and understand what is already excluded. What is not
STFC-RAL-CR03 R61: this way we prepare ourselves so possible signatures, possible
STFC-RAL-CR03 R61: interesting stuff, and we'll be able to make a classification. Make make an identification of that message. That's what I was doing for the last, like 1015 years.
STFC-RAL-CR03 R61: And well, there is a lot of papers. Well, I'm lucky with my collaborators, actually. And well, several papers coming this year.
STFC-RAL-CR03 R61: and some of them they well already are in a stage of submission. And I will mention this.
STFC-RAL-CR03 R61: Yeah, now talk about adapted candidates and maths.
STFC-RAL-CR03 R61: So the well, I'm I'll read this. It's 10 to the minus 36 Gb. And this is 10 to the 1110 to the 21 gb, so that's my
STFC-RAL-CR03 R61: has a huge span as well as interactions in, think about this, how mathematic could interact with problems. Well, that'll remind them 39 extremely weak. That's the 24 extremely strong. But okay, this will be different models.
STFC-RAL-CR03 R61: If we talk about the standard ribs just to kind of make it more concrete. Then we concentrate it on this little kind of quadrants. Well, it's hard to see. But in principle. Well, there is a Oh, I was told that there is okay. So I just want to draw
STFC-RAL-CR03 R61: that. This case is very simple. So the direct detection experiment. Well, this is the muscle dark matter.
STFC-RAL-CR03 R61: and those are the strengths of digital. It's
STFC-RAL-CR03 R61: actually doesn't. It's it's not sensitive to the light dark matter, but then become more sensitive to the header depth method.
STFC-RAL-CR03 R61: And the large Henry Collider is actually, it's opposite. So it's kind of it's sensitive to the load up method. But then it's not sensitive to the
STFC-RAL-CR03 R61: heavy
STFC-RAL-CR03 R61: that matter. And this is what drawn here. They're they're very complementary. So this is the this is the Lhc.
STFC-RAL-CR03 R61: and this is a dark matter, direct detection. So that's usually what happened.
STFC-RAL-CR03 R61: And the big sketch.
STFC-RAL-CR03 R61: And actually, well, this guy like she's blue here as well, but anyways.
STFC-RAL-CR03 R61: random pickup power. But the the quality of picture is there. So
STFC-RAL-CR03 R61: now another like note about the implementation of different searches. We have not only Lhc not only direct detection, we have well this kind of picture, well, assuming that that might be interactive standard model
STFC-RAL-CR03 R61: with the coupling, which is not negligible, not negligible, means the coupling, although there may be even 10 to the minus 5, still not gravitation. So.
STFC-RAL-CR03 R61: and that matter well, if you turn the background, I mean any direction. For example, if you go in this direction, this is during the it's direct deduction.
STFC-RAL-CR03 R61: and else that have a fantastic result which is growing with previous kind of searches from the previous year. But other magnitude. I will show some example how important this issues
STFC-RAL-CR03 R61: the if you look at this direction that met, angulated
STFC-RAL-CR03 R61: dynamic, that matter can manipulate to certain other particles in this code
STFC-RAL-CR03 R61: indirect detection, not only in direct detection, but also well, there are some. If you consider that integration in the early universe as a Cmb. Time.
STFC-RAL-CR03 R61: it's called Cmv. Constraints. And these constraints. It's called indirect detection. Cm. Constraints, because these constraints are very much robust. Why, there's no galactic structure, the Cmv time.
STFC-RAL-CR03 R61: and therefore there's no uncertainties on the propagation of document products in the universe, and that matters.
STFC-RAL-CR03 R61: injects to stand the model particles, injects their energy into interstellect media. It it can delay recombination.
STFC-RAL-CR03 R61: but recommendation. Time is measured with better than per minute precision. That's why
STFC-RAL-CR03 R61: it's the constraints. Only Indian constraints are very sensitive.
STFC-RAL-CR03 R61: and of course, if you look at this direction
STFC-RAL-CR03 R61: collide as a model particles in the form of protons so polytones. You can think about colliders producing direct matter.
STFC-RAL-CR03 R61: and there is a standard
STFC-RAL-CR03 R61: more than but not only it could be some soft left and stuff which is also very typical, for that matter. And we need to deal with this.
STFC-RAL-CR03 R61: So bottom line is that all these directions are complementary. They're not 100% related.
STFC-RAL-CR03 R61: That's very important, and that just allows us to look at document and signatures in from different perspectives.
STFC-RAL-CR03 R61: Talking about the theory stage.
STFC-RAL-CR03 R61: It's another look from at the series. And I stolen this. This is very old slide from 2 page which I like that is more new, new his own stuff. So you can start from effective theories, which has only, like one parameter or 2 parameters.
STFC-RAL-CR03 R61: and go to the simplified model with few parameters and go to the other. One is complete model, with maybe dozens of parameters. So maybe 100 parameters as a Ms. Sample. But so there's a number of the number of parameters increasing.
STFC-RAL-CR03 R61: And also one can think about consistency of this model which I will mention about this.
STFC-RAL-CR03 R61: So I like this kind of area because this area corresponds to the theories which are already not effective models. Those are really real models which can be already models of nature without any extra stuff.
STFC-RAL-CR03 R61: Excellent stuff, maybe you need to add, but it can be like, you break already fundamental model right here.
STFC-RAL-CR03 R61: And that's why. And these models have a not too many parameters.
STFC-RAL-CR03 R61: And so I will start with the
STFC-RAL-CR03 R61: kind of see potential to probe that matter. So I'm reviewing
STFC-RAL-CR03 R61: some papers, not all of them, and well focusing on some kind of published.
STFC-RAL-CR03 R61: I think it's important.
STFC-RAL-CR03 R61: So of course, if you produce 2 fair of that matter. You know that.
STFC-RAL-CR03 R61: You observe nothing, because that matter behaves like neutrino. It's it's interacting. You don't see. But if you radiate blue, you get standard monitor signature, and then, or, more important, whatever you already so valid, recording, invisible document. So that's the what you see in the picture question is that with this simplistic picture, can you tell anything about that matter from the first? st Look? Well, you can see that if something recording
STFC-RAL-CR03 R61: chat not much much to tell. However, you can actually look at different rates. This is the
STFC-RAL-CR03 R61: effective theories, but still we can decode different
STFC-RAL-CR03 R61: information. I mean, you can distinguish. There's a well. 5. There's a curators for different dark matter spins. So this is
STFC-RAL-CR03 R61: well, the operator. This is the scarf
STFC-RAL-CR03 R61: structure. So this is the scalar current. There is no any Lorentz structure here. This is just a contact in direction.
STFC-RAL-CR03 R61: Here you can put down a new. This is vector. Currents for reference. Well, so for the thermonic and sorry for the scalar and thermonic data, and then the even tender structure. So these operators are here. So, for instance, can we distinguish these directions? That's by looking at the monitored signature?
STFC-RAL-CR03 R61: Well, naive answer. Maybe not. Because it's like too simplistic. But actually, you can have a power of the differential distribution
STFC-RAL-CR03 R61: to look at the differential solutions and think about what you can. Kind of can play.
STFC-RAL-CR03 R61: Let's about. Let's think about that.
STFC-RAL-CR03 R61: Suppose the that method invalid mass. Let's think about that matter. Environment, mass, you produce some that matter with the environment mass.
STFC-RAL-CR03 R61: And let's consider the case when the line mass is small.
STFC-RAL-CR03 R61: when the large mass is small and you relate something hard. What we learn from densities is that the shift of the Delta X, for in for the part, density function
STFC-RAL-CR03 R61: will be large. If this is small and you add something hard. This environment, the whole system will change by a lot. Because this mass is small, you need hard.
STFC-RAL-CR03 R61: the master. The amount of mass OS hat will be changing by a lot, and therefore Delta X.
STFC-RAL-CR03 R61: The the change in the pipeline message will be large.
STFC-RAL-CR03 R61: and then, if you, if you, if you change Delta X by a lot, if the your prospects and department will be falling a lot, because if you have a small X
STFC-RAL-CR03 R61: go to live, app is falling secret.
STFC-RAL-CR03 R61: They open the case when you have large environment of that matter.
STFC-RAL-CR03 R61: and you have already already something.
STFC-RAL-CR03 R61: Then the the total environment of the system does not change market, because we already have a heavy beach here.
STFC-RAL-CR03 R61: so the Delta X will be
STFC-RAL-CR03 R61: change will be small. So from
STFC-RAL-CR03 R61: that one delta X to slightly bigger delta X. The the slope will be much
STFC-RAL-CR03 R61: kind of milder, not very steep, and then so therefore you expect, if that matter in light mass is small here, so this load will be
STFC-RAL-CR03 R61: well for a steeper, steep, steep slope, and rail more at that time, so
STFC-RAL-CR03 R61: if some actuator prefer small amount of mass of dark matter, then you, you will expect difference between the curator which lead to the small amount of mass of that matter and large amount of mass of that matter.
STFC-RAL-CR03 R61: and that's what we'll observe.
STFC-RAL-CR03 R61: Actually, that's exactly what we observed. So for
STFC-RAL-CR03 R61: vector, document, which is dotted lines, sorry, it's not very visible. But okay, this is dotted line. The slope is the most radial. So it's and for a scalar dark matter the slope is quite steep here. So this means that actually you can already use by looking at missing a T with her monitor. You can, access
STFC-RAL-CR03 R61: well understand the nature of the iterators.
STFC-RAL-CR03 R61: and these are the missing meeting. So this actually theoretical flow.
STFC-RAL-CR03 R61: this is environment, parts of that matter, distribution which you cannot measure experimentally. But you can actually see that you can correlate. You can calculate environment parts of that meta distribution. This is, this is the biggest one for vector dark matter. And this is the and the smallest one for scalar data.
STFC-RAL-CR03 R61: And you can see that the projected document
STFC-RAL-CR03 R61: for certain iterators. Okay, it's very detail. But it's a bigger. So the mean value of the line mass is bigger, so you can correlate this slope with the one of the most kind of gradual slopes there.
STFC-RAL-CR03 R61: So there's well, the actually the purple one is the giving the most gradual flow. But there is a correlation between environment.
STFC-RAL-CR03 R61: and they move radial slope. So you can distinguish the period
STFC-RAL-CR03 R61: that's important, and this would be well, it was a big puzzle for us. Why, actually missing a T or in one of it from super symmetry, is more flat than the background. Coming from that standard model, that going to neutrinos.
STFC-RAL-CR03 R61: It's simply because the amount of mass of neutrinos, which is zon, is smaller and falling quicker.
STFC-RAL-CR03 R61: Then environment. Does that matter coming from super symmetry? That's why it gives us have the power to
STFC-RAL-CR03 R61: analyze the shape difference, or maybe a 5 p. Cut and and cut away background.
STFC-RAL-CR03 R61: Well, I would like to talk about that method classification. It's very important to classify that method, classification, and other systematically
STFC-RAL-CR03 R61: explore it, understand? And decode about. If you've got some signal, you can say, Okay, this is signal from that kind of class of document. And you can actually well identify it if you prepare yourself.
STFC-RAL-CR03 R61: So we need to prepare ourselves. We need to manage that ridiculous application
STFC-RAL-CR03 R61: here. I had my own bit
STFC-RAL-CR03 R61: and minimal, consistent documented models. What it is.
STFC-RAL-CR03 R61: Well, we require that that many models should be the agent. Environment anomal is free
STFC-RAL-CR03 R61: and well, have a kind of at most one mediator multiple. So which means that we consider generic
STFC-RAL-CR03 R61: glass of kind of generic scheme. We have that matter in the multiplets. So including singlets. So singlet, triplet
STFC-RAL-CR03 R61: and mediator multiplet again, single double triplet. And this is like a the minimum set of model.
STFC-RAL-CR03 R61: And they are different from simplified model, which is often not anomaly free, not gauge in variance. Sometime you just add that prime which integrates with that matter. And if you're adding the prime without providing mechanism of that prime margin. Actually, you usually break gauge invariance. So this minimal, consistent model. They can be
STFC-RAL-CR03 R61: a building block, or they can be fundamental models by themselves. Actually. So we did this some time ago with Jackman and my
STFC-RAL-CR03 R61: and the Channel classification scheme.
STFC-RAL-CR03 R61: So there's a letter which you will well, which indicates some letter X which indicate the ISP. And hyperchard essentially says that well, either spin tells how big multiple that is.
STFC-RAL-CR03 R61: have a good show.
STFC-RAL-CR03 R61: What? How, what's the interaction with that button essentially is, and and
STFC-RAL-CR03 R61: in terms there will be 2 letters 1st letter corresponding to oh, maybe I'll
STFC-RAL-CR03 R61: 1st letter, for example, this is killer corresponding to the acmeta multiplet and the second letter to mediator multiplet.
STFC-RAL-CR03 R61: And eventually, if we consider
STFC-RAL-CR03 R61: that matter here, and my data here will be well, just a table, 3 by 3. So spin 0, for that matter, one half, for that matter, one, for that matter.
STFC-RAL-CR03 R61: and and speed till one half and 1, 4 million. Is there a reason to exclude gravitinas, the gravitinas? No, it was a yeah. We can we can do this? 4 by 4. Yeah, yeah, we simply, yeah. There was a lack of manpower. Yes, gravitinas are fine.
STFC-RAL-CR03 R61: Good though. The thing is, they are kind of weaker, interacting, much weaker, interacting with gravity kind of
STFC-RAL-CR03 R61: related to gravitational direction. And usually you can actually calculate the relative density of the next slightest particle to Gravitina.
STFC-RAL-CR03 R61: which usually they have a my speed one, for example, what everyone have low speed and
STFC-RAL-CR03 R61: estimate, they are very 10. But yes, you're right, absolutely. Yeah. And
STFC-RAL-CR03 R61: another thing that I would like to say is that, if you consider that and ultimate only this interesting thing, because well, by gauge events, all these particles. So the charge and in the middle have 0 charge, and the at the bottoms have minus
STFC-RAL-CR03 R61: all these particles at 3 level. They have identical mass, which is not good, because well, if we, if we have charged components
STFC-RAL-CR03 R61: Has the same as a document, and then we have charged particle charge document.
STFC-RAL-CR03 R61: It's not good, but luckily we have a quantum nature of our world.
STFC-RAL-CR03 R61: and there is a mass split between charged particles
STFC-RAL-CR03 R61: and the nuclear particles, which is document
STFC-RAL-CR03 R61: sometime charge speed works in the bad way, because sometimes well depending on the charge selection. But in this simple, simple case in case of, say, doublet with a certain charge the charge guys hate it.
STFC-RAL-CR03 R61: And this is the example of the indication which splits the mass of the general charge Guy, in comparison to the joker.
STFC-RAL-CR03 R61: So it's here thereby about actually about 5 months more precise, it's mass math of W. Times.
STFC-RAL-CR03 R61: Alpha squared over 16 pi. 4. And you got immediately about 280 thing. When I talk to Stuart. It's amazing that actually, Peter.
STFC-RAL-CR03 R61: maybe before, like 5, 6 years ago.
STFC-RAL-CR03 R61: maybe more. But I remember I was talking to. He did not incorporate the proper lifetime, because they told me so that the 100 Mev. Is not natural, and it must scale, for all this part has been stable.
STFC-RAL-CR03 R61: and they say, well, the 3rd term is just MW. Times Alpha Square, alpha width squared over 16 piss little correction. And that's this natural scale case. And this particle became long lived, and it gives rise to a disappearing charge, for example, because we produce charge guys.
STFC-RAL-CR03 R61: they are long lived. They dedicate to very soft time like.
STFC-RAL-CR03 R61: So the or whatever you you may be fine, then it may be fine, and that matter
STFC-RAL-CR03 R61: so track disappeared because that method is invisible. But well, 50 whatever maybe 5 is also not visible, because it will be code in the automatic field, though there are some attempts to to. Look at this closer
STFC-RAL-CR03 R61: here. I don't. I mean, I just want to message of this block is the following, this is the dark metamass, and this is the the section, and this is the latest, one of the latest result.
STFC-RAL-CR03 R61: And it's becoming sensitive to some models.
STFC-RAL-CR03 R61: But even at the loop level, because that matter interacts
STFC-RAL-CR03 R61: with the problem. I mean this, this is that matter, and this is cool
STFC-RAL-CR03 R61: and in all models nowadays I mean the model
STFC-RAL-CR03 R61: which interact directly, not the loop level with the program they excluded.
STFC-RAL-CR03 R61: So the only like sensitivity comes from the
STFC-RAL-CR03 R61: loop interaction. So the loop induced interaction between document and proton work are not excluded, but
STFC-RAL-CR03 R61: most of them actually even those a lot of models of this class are excluded.
STFC-RAL-CR03 R61: So this is the example for some models, and actually include quite a lot of model. But there are some cases
STFC-RAL-CR03 R61: where there is a cancellation between loops and some model like this become even below the nutrient flow. So you cannot exclude this possibility.
STFC-RAL-CR03 R61: Well, that's the message. I don't want to come too much details on that.
STFC-RAL-CR03 R61: but it also impressive. The integration to fund directs the has a lot more than one other compute effects. So it's why it was impressive.
STFC-RAL-CR03 R61: Excluding that I'll I'll count also for this.
STFC-RAL-CR03 R61: And as a result of this classification we found already some time ago, the model, the one of the more simplest model when you have a
STFC-RAL-CR03 R61: singlet matter interacting with the to the scalar. So this is the to the scalar, a direction with the terminal, and this to the Scalarman direction. This is like a another term, we should allow, so they're both singlet. So again to a, to the scalar, and psi is the is the terminal
STFC-RAL-CR03 R61: and hosting. It
STFC-RAL-CR03 R61: comes out that this simple model was missed. And what's happening is that the both to the scale of and and the ferment can become a dark matter.
STFC-RAL-CR03 R61: Well, there's a kind of accidental stability, but actually, nothing is accidental in our world, because well, there's a conservation of CPU number kind of sector. So a diagram which you need to calculate in order to evolve reading density is related to size. This is the the term amounts, and relating to say, Hicks and a
STFC-RAL-CR03 R61: you put this into micro megas. This is a package package which automatically well, it's very density. You put it per common groups into cloud shape for one graph well, agrature
STFC-RAL-CR03 R61: calciap, because calciap is an engine core engine for micro makers.
STFC-RAL-CR03 R61: And I'm also biased because I'm also
STFC-RAL-CR03 R61: okay. So you put the time in those and you're basically done succeed.
STFC-RAL-CR03 R61: I don't.
STFC-RAL-CR03 R61: And this is a text about on for the founder X, which so we have some parameter space which dictated by, say, through the a through the HA well.
STFC-RAL-CR03 R61: or some different diagrams, a a through H, so they have 2 components of dark matter. You have side, and a this is the so. This is the relative density for the side, and this really density for the a
STFC-RAL-CR03 R61: eventually in and there are some they should provide the right one. But there is a certain structure, I mean, I probably will not go into details. But if you sit on the h resonance, aa, so the a mass is kind of fixed to be horizontal. So you're sitting on the Higgs resonance. And this diagram actually work providing relegence
STFC-RAL-CR03 R61: because the whole game of the story. It's very hard to provide
STFC-RAL-CR03 R61: lower density. Only physics is heavy, so heavy particles means low perception. Low cross section means higher density.
STFC-RAL-CR03 R61: Why? Because early universe. Maybe I should explain this. I mean, in in the earlier universe we have a super part.
STFC-RAL-CR03 R61: and including that matter, then you know, schools and that matter plays out.
STFC-RAL-CR03 R61: If a anegulation cross section of dark matter to standard border particles is low, there will be a lot of particle, a lot of dark matter particle left and the universe will be over about. So you need to provide effective annegation channel
STFC-RAL-CR03 R61: of that method to the standard model particles in order to have a right amount. Right? Demand is kind of low. Because typically it's hard.
STFC-RAL-CR03 R61: That's why it keeps alligating this one of the channels. And this is. That's why the points it's concentration here. There's also
STFC-RAL-CR03 R61: and coagulation of that. A and psi, that's right here. But yes, so
STFC-RAL-CR03 R61: if you, this is old result. Now, if you plug in Lz results.
STFC-RAL-CR03 R61: you end up with this. So this is how a direct detection works as it ex- excludes almost all parameter space.
STFC-RAL-CR03 R61: Well, it still left something. There's a little copy. But yeah, so it's most most of the resident.
STFC-RAL-CR03 R61: And both options left.
STFC-RAL-CR03 R61: Another thing how to test this model only direct detection, and it's not very exciting. Well, that Lec cannot test it, but only maybe to the loop is used invisible key SDK,
STFC-RAL-CR03 R61: so the loop is. So he goes to type side only through the loop.
STFC-RAL-CR03 R61: and there is a red line is the right amount of credit density.
STFC-RAL-CR03 R61: Well, some sometimes master speaks, and Atlas, or whatever this is, Atlas limit limit for 7, 7% and Cms is similar so it can.
STFC-RAL-CR03 R61: Besides, at the moment with a little anticipated parameter space, high velocity, I would see if I assume
STFC-RAL-CR03 R61: this is already.
STFC-RAL-CR03 R61: So this is this was 10%. Now, I'm assuming 7% of few percent. Actually, 1, 2, 2, 3, 4, 4% for handling.
STFC-RAL-CR03 R61: Well, maybe call. Do you agree? Well, well, roughly, few percent. Then you can cover slightly more
STFC-RAL-CR03 R61: if you well plug in Ilc, which I'm not sure when it will be. But at least, if you assume that some high precision. Experiments will test invisible Ttp up to few per mil. Then it can cover up to here. But you cannot really exclude it
STFC-RAL-CR03 R61: so, and we're testing loop in music. So it's but amazing that we still can can do something.
STFC-RAL-CR03 R61: And
STFC-RAL-CR03 R61: one more must mention in decoding document at future request, because I still think that there is a very
STFC-RAL-CR03 R61: important power of linear colliders to has the nature documented. So I appreciate that we see. So it just kind of want to say that. So we have 2 famous, well well known model. One is inert to keep double
STFC-RAL-CR03 R61: where we have standard model doublets
STFC-RAL-CR03 R61: and no doublet are not required. That's why these particles got some quality stability. So because, did mention that that mathematically stable and there should be some conservation of some quantum number
STFC-RAL-CR03 R61: programming disability. And this is the the 2 symmetry.
STFC-RAL-CR03 R61: Well, similarly, I mean, the environment diagrams are the following.
STFC-RAL-CR03 R61: so what you have, you have.
STFC-RAL-CR03 R61: and t. 1, which is that matter, d. 2 is the next
STFC-RAL-CR03 R61: have a neutral value, and the plus the minus well. The is the charge
STFC-RAL-CR03 R61: guy, which decays to eventually the decay can decay to that point, and that one
STFC-RAL-CR03 R61: and very similar for minimal thermionic models has a very similar structure. So there's A. D. 2. Well, well, this the only thing is d. 3. But let's let's not go into details. Essentially, it's d 2D. 1. It's another analogous to. Well, neutral dark matter in the next neutral dark. And again, the plastic lines. It's very similar kind of structure, and
STFC-RAL-CR03 R61: and well, conceptually by parameters. Well, for 12 theory. It's different.
STFC-RAL-CR03 R61: and it parameterized by dark matter. Mass in the mass fleet between charge guard and dark matter.
STFC-RAL-CR03 R61: Also the mass split between the second neutral drive and the charge driver. So this is the 3 parameters benefit of this model. Very simple model.
STFC-RAL-CR03 R61: This model is actually challenging at the Lfc.
STFC-RAL-CR03 R61: Because it leads to the soft platin, I mean, how think about that? The dark matter is say, for example, 100 Gb. Or 120, and the next guy has a small mass literally dictated by different arguments. But.
STFC-RAL-CR03 R61: for example, delta parameter and procedure data, so it leads to the. So if you produce pair of these guys at large can decay, you can see how it will decay. It will decay to. You can do it back so to that virtual Z and d. 1, and this virtual that will have a mask.
STFC-RAL-CR03 R61: A few dozens of, say, 2030 g. In there will lead to result.
STFC-RAL-CR03 R61: And this is the problem. But in principle is you can handle this. But Linux can handle better
STFC-RAL-CR03 R61: so. But there also one big difference in comparison to.
STFC-RAL-CR03 R61: would say that this mode d plus d minus is the I mean, has a lot of background
STFC-RAL-CR03 R61: and not favorite. It's most model independent, because the must be the one they do is model dependent.
STFC-RAL-CR03 R61: It's how I arrange parameters of the model. But here we have photon which always interact with the charge guy. So the cross section is given only by the mask. That's it. There's no any other model parameter.
STFC-RAL-CR03 R61: and I will see you can prove this signature. So the idea is that to produce payroll, the plus the minus, which then decay to dark matter and double plus double minus
STFC-RAL-CR03 R61: and hold some semitone tablet, but we can reconstruct double.
STFC-RAL-CR03 R61: and the idea is to look at actually angular distributions of double
STFC-RAL-CR03 R61: besides angular distributions, you can distinguish rate by a spin factor. So the the the cross section of the
STFC-RAL-CR03 R61: Scalar Guide will be about well, about factor of not about well, 5%, the factor of 4 lower.
STFC-RAL-CR03 R61: then the thermometer. This is the steam factor.
STFC-RAL-CR03 R61: Besides this, there was a interesting differential distribution. So this is absolutely the cross section.
STFC-RAL-CR03 R61: which is good. But you can do much better.
STFC-RAL-CR03 R61: We can look at the angular distribution of doubles
STFC-RAL-CR03 R61: from this escape from the blasey case in case of
STFC-RAL-CR03 R61: well, this is the scalar document that is to be normalized distribution. So
STFC-RAL-CR03 R61: so, yeah, this is the yellow documents.
STFC-RAL-CR03 R61: And this is the learning document. All distributions are normalized
STFC-RAL-CR03 R61: and background is well, behave like this.
STFC-RAL-CR03 R61: And you can handle with not only background discrimination, but also discrimination between scalar and very nicely. And this comes from the actually diagram structure. So yes. Well, background has a feature of production. Well, and but because of spin of that matter.
STFC-RAL-CR03 R61: the scalar actually distribution. We're looking at the double distribution in the in the log frame. So just look at the the log in the log frame, the angle, angular distribution of double bottom.
STFC-RAL-CR03 R61: Quite amazing. You can actually tell what spin of that method you can decode this.
STFC-RAL-CR03 R61: Let's go. So sorry about that last model. Was there any reason not to be
STFC-RAL-CR03 R61: talking about it in the Lfc context.
STFC-RAL-CR03 R61: Yes. Lhc is sensitive to that. Yes, kind of skipped. Yet we did analysis of the Lhc. And in fact, this would be related to the contact context of you know, the outlook model. And this is.
STFC-RAL-CR03 R61: and the Lhc background is is large, and for for particular masses which we've chosen. Lc, is not sensitive because of soft electrons coming and background. The the problem is the soft electrons you need to reconstruct.
STFC-RAL-CR03 R61: If you go to the harder, the bigger mass difference.
STFC-RAL-CR03 R61: then the cross section drops to to too much, and that's it. I mean that that's kind of.
STFC-RAL-CR03 R61: There's no free lunch. You have something further than you have a low perception
Chris Damerell: Excuse me, what energy! Linear Collider do you have here
STFC-RAL-CR03 R61: Oh, yeah, thank you for question. Here we still be 500 Gb. Provider. So we've been optimistic
Chris Damerell: Okay. Thank you.
STFC-RAL-CR03 R61: Yeah, yeah, yeah. Think it's important to when I was there, maybe one demand. Well, in in 90
STFC-RAL-CR03 R61: 3, when I finished my diploma work at Moscow State University. The diploma was devoted to production of exciting neutrinos at Ilc.
STFC-RAL-CR03 R61: and this was a long time ago. It was 30 years ago already right. So, and that time I was sure that now we will have, and it's a shame that we don't that kind of thing and still hope that, maybe.
STFC-RAL-CR03 R61: Yeah, I'm happy with Lhc, but I think we can do even better this, this, okay, there's objectives. But I don't want to go to politics. I just want to say that the physics, in combination to discover but distinguish. There are some particular cases, and you have can have also discovery power for this.
STFC-RAL-CR03 R61: So beyond the week interactions, let's go beyond week for certification. So one of the thing we tried is go beyond 2 week.
STFC-RAL-CR03 R61: and we we look at the dark 2 group. So for dark issue, we actually look at the vector, document coming from dark group
STFC-RAL-CR03 R61: so what are the ingredients? But before that I just want to kind of as a context. So the fact that matter was explored.
STFC-RAL-CR03 R61: but mainly, actually a billion coming from you. One group. And this is the idea that we have some available one group
STFC-RAL-CR03 R61: which got broken by the Hicks.
STFC-RAL-CR03 R61: And then we have vectors, so we can arrange stability of it by just implementing. There are some papers.
STFC-RAL-CR03 R61: So what we we did is, 1st of all, let's go to non available group. Let's go to the beyond the Hicks portal, portal. Approach. Why? Because Hicks Portal has a actually
STFC-RAL-CR03 R61: oh, there's some meetings within 5 min. Okay, this is good. Okay. The the vector dark matter
STFC-RAL-CR03 R61: within the possible to get rid of that somehow, it will go away it will go away. Okay.
STFC-RAL-CR03 R61: still, kind of it. So 0
STFC-RAL-CR03 R61: 2 main thing in in the, in the limitations of his portal.
STFC-RAL-CR03 R61: 1st of all, I mean, there are 2 competing things
STFC-RAL-CR03 R61: 1st of all, colliders, or say even direct detection push the coupling to be lower than something, because well, direct detection
STFC-RAL-CR03 R61: this is in, and this is the blue one.
STFC-RAL-CR03 R61: And actually, it's not even more than one, because more than one probably will go, even almost excluding this up to this date. So this is one year ago. Right? So this one.
STFC-RAL-CR03 R61: everything about this blue line is excluded. So this coupling of the Higgs interaction with the vector document, which is portal coupling must be below this from the point of the direct detection, because we don't observe things. On the other hand, if the company is too low, the ratings will be too high, so ray density requires actually to be above the red line or on the red line. No, but not below the red line. If you're below the red line.
STFC-RAL-CR03 R61: the array density is too high. So what is left is only this little tip, and nowadays I mean, if you increase the sensitivity by Factor 10 that will be probably even less something like this. It will be less
STFC-RAL-CR03 R61: with Alpha storage. So this means that they're almost included. I mean, this is like a kind of
STFC-RAL-CR03 R61: I wanted a scenario where the executive background with the keys photo.
STFC-RAL-CR03 R61: So
STFC-RAL-CR03 R61: because the message is that the heaps. Portal is very limited because of interplays getting detection and everything else.
STFC-RAL-CR03 R61: What we suggest is to use completely different route.
STFC-RAL-CR03 R61: Well, we suggest to have the 2 dark gauge triplet. This is the vector we have some complex scalar because we need to break the symmetry and make it heavy like a Higgs making doublet, but heavy, massive. So we need the doublet which break the symmetry.
STFC-RAL-CR03 R61: And we need a portal.
STFC-RAL-CR03 R61: new portal, and the new portal is a vector like 3rd bound, which in interacts with actually, and the model terminus with the portal. So there are 3 ingredients.
STFC-RAL-CR03 R61: And well, I wanted to explore this. So the the rest of my talk, which is like 1015 min, not more
STFC-RAL-CR03 R61: do I have like 1015 min, or something.
STFC-RAL-CR03 R61: I will talk about that, because this is my favorite baby, because it's really new classic models which we working now.
STFC-RAL-CR03 R61: So
STFC-RAL-CR03 R61: we signed the charge to to the tablet. Probably already when I get to the most interesting point, but I will try to make it kind of slow.
STFC-RAL-CR03 R61: So the tablet has some that charge and the key point. The central point is this Yuca interaction.
STFC-RAL-CR03 R61: So do you have interaction? Maybe I'll write it here just
STFC-RAL-CR03 R61: and then what do you have?
STFC-RAL-CR03 R61: And
STFC-RAL-CR03 R61: we have the following thing.
STFC-RAL-CR03 R61: We have a new, better life term and doublet, which is called sorry, or maybe F.
STFC-RAL-CR03 R61: Yeah.
STFC-RAL-CR03 R61: Mv.
STFC-RAL-CR03 R61: And F.
STFC-RAL-CR03 R61: We have a 3 min or back to one week with last.
STFC-RAL-CR03 R61: and we have a heat.
STFC-RAL-CR03 R61: That piece which is so after this is SSD,
STFC-RAL-CR03 R61: 5 HD. After symmetry rating what happened?
STFC-RAL-CR03 R61: You get very similar thing that that web was heard of, too.
STFC-RAL-CR03 R61: Okay, so the thing is that all degrees of freedom will be eaten by these these guys, I mean. And so the only one degree of freedom back keeps that keeps left very in the same analysis
STFC-RAL-CR03 R61: than a month.
STFC-RAL-CR03 R61: And let's take a look. So
STFC-RAL-CR03 R61: how this model communicates with standard model. It's just done by your color coupling. It's why called White Prime.
STFC-RAL-CR03 R61: We we call it sidebar. It's a doublet.
STFC-RAL-CR03 R61: the 5 keys. This is also doublet, so it's consistent with the gauge symmetry, so doublet, doublet, and singlet. This is right. Determine from standard model. So this is the standard model, and this is the
STFC-RAL-CR03 R61: that sucked.
STFC-RAL-CR03 R61: and you can write it because, well, by by group symmetry. Anyways, this, I think probably the only well.
STFC-RAL-CR03 R61: but rather know right? So I don't want this to experiment with it. But this is the kind of very simple repository.
STFC-RAL-CR03 R61: And the thing is that let's discuss quantum numbers
STFC-RAL-CR03 R61: well, the thing is that if I assume that the
STFC-RAL-CR03 R61: 5 side has a dark charge. Let me- let me just
STFC-RAL-CR03 R61: stress this. So they- they have a dark well, it's a double screen, and I'm assigning the charge dark charging conservation.
STFC-RAL-CR03 R61: and you can see that the upper component of this doublet has a
STFC-RAL-CR03 R61: that charge plus one. But lower component of this doublet has 0 that charge.
STFC-RAL-CR03 R61: Well, because deduct charge is goes like this, deduct is equal to
STFC-RAL-CR03 R61: either speed. Well, fiber charge plus 3 3rd component with the dark either spin. And this is dark.
STFC-RAL-CR03 R61: Whoa!
STFC-RAL-CR03 R61: Talking about the electromagnetic charge these ferments, both of them
STFC-RAL-CR03 R61: as the same chart as the retinent of standard model.
STFC-RAL-CR03 R61: Think about, for example, you can choose any stock, for example, if you choose the stock, they will be kind of stop partners. They have the same charge at this as in this.
STFC-RAL-CR03 R61: And interestingly, what happened with the Jupiter.
STFC-RAL-CR03 R61: The triplet has the same. Well, kind of structure. It has a well, the component of the either spin plus 1 0 minus one. Therefore that charge
STFC-RAL-CR03 R61: plus 1 0 minus one.
STFC-RAL-CR03 R61: So these guys, the T plus and the minus, this is the dark charge. They carry that charge which is conserved, so if they have the largest one
STFC-RAL-CR03 R61: they will be stable. So this is our document.
STFC-RAL-CR03 R61: It's a doctor.
STFC-RAL-CR03 R61: Why, this guy does not carry that charge, and if you can call the prime Z. Prime, or whatever it can actually mix with the problem of that because they're quantum numbers. It doesn't carry that
STFC-RAL-CR03 R61: that joke. This is the key point.
STFC-RAL-CR03 R61: And so it's interesting that among components on the back of that.
STFC-RAL-CR03 R61: this and these are, document the candidate
STFC-RAL-CR03 R61: well, and I put it in red. So just to make sure. And this is the 0 I put in blue because it doesn't carry dark charge. So this is like more standard one. This is the prime 0.
STFC-RAL-CR03 R61: So
STFC-RAL-CR03 R61: good. Any questions about that, because this is like this is the only like the most difficult conceptualization. And and this is the thing which makes this model very interesting from theory and physiological point of view from experimental point.
STFC-RAL-CR03 R61: Don't you risk flavor changing neutral currents of these things? No, because it depends on okay. It's up to me if if I choose. This only one milliliter like, say, top
STFC-RAL-CR03 R61: and vector lacto. Then answering is no, I can put several mediators in mix, and then your power will be kind of flavor containing flavor, because I put several, then I can mess up. But in the simple construction, no, no.
STFC-RAL-CR03 R61: and this is how this looks.
STFC-RAL-CR03 R61: So the the Lagrangian looks like this. So this is the key point. This is your character. But I better go and look at writing this complicated Lagrangian. So what what interactions you have in this model. This is interact. The red one are guys which carry that chance which is concerned, like all particles in 2 symmetries. So the this is therefore V is that Meta
STFC-RAL-CR03 R61: v. Primes is like a Z primes which can decay, which can decay. I'll tell us why, but and you have some different vertices. You have a vertex. So you, and also
STFC-RAL-CR03 R61: indeterminant doublet. That's a very interesting thing. I I will change the cover because the the upper guide has a double charge, but lower does not have that charge, and the actual lower drive from this doublet mixes with standard model terminal
STFC-RAL-CR03 R61: and the upper guy, since it scares that charge, you can still that kind of like indicating it's all it's getting some quantum numbers, which is quantum numbers.
STFC-RAL-CR03 R61: So they still don't appear, but
STFC-RAL-CR03 R61: upper terminal carries our charge. Low terminal, which meets with standard model terminus does not.
STFC-RAL-CR03 R61: So bottom line is that you have different vertices and a different interaction. So
STFC-RAL-CR03 R61: but they're they're quite simple. And from conceptual point of view, another thing that deep right?
STFC-RAL-CR03 R61: Because it doesn't carry that charge via loop can mix with the folder and so forth.
STFC-RAL-CR03 R61: The product numbers of this guy.
STFC-RAL-CR03 R61: The same is, say, a standard model product.
STFC-RAL-CR03 R61: and this diagram just show the mixing between side r and side left well, etcetera, etcetera. But there is a mixing basically by kicks insertion.
STFC-RAL-CR03 R61: You you can meet so essentially this, you power coupling is nothing but leaves nothing but the same, the whole background. So this will be side.
STFC-RAL-CR03 R61: What? Okay? This is F mixes with the
STFC-RAL-CR03 R61: So this is MLMR. Something like this. So this is just tells us that whatever terminal you choose for the portal.
STFC-RAL-CR03 R61: and you you can actually mix. For example, you choose top 4 top right for the top, right here, and top partners here. This means that the heavy top. One of them will be meeting with the top right? That's it will be mixing. And this mixing should not be very large. But yeah, it it can be.
STFC-RAL-CR03 R61: And one of the provider signatures would be the following, so you, you can produce top partners this term of default. This is the some computer realization with the top portal, with the keys to top. And the so this is the exactly well, driven by
STFC-RAL-CR03 R61: by this vertex. So this is that you produce all the top which indicates the top.
STFC-RAL-CR03 R61: And that matter.
STFC-RAL-CR03 R61: So this is this is the diagram here, so it will be teacher bar plus missing.
STFC-RAL-CR03 R61: And you can produce photos when we branded into the bar. But there are actually more interesting, exciting signatures that we'll be talking about.
STFC-RAL-CR03 R61: Now we ask ourselves, what if instead of top partner, we'll choose neon partner. So now we choose. This is the model neon.
STFC-RAL-CR03 R61: and this is the Milan doublen doublet.
STFC-RAL-CR03 R61: The idea was that maybe we can explain Z minus 2 anomaly, which is maybe not anomaly nowadays. We don't know. But I'm I'm still
STFC-RAL-CR03 R61: taking kind of agnostic point of view, or let's wait till the like. Well, that's settled. But so there's still contradiction, at least in E plus and minus data to for interaction processes. We can, we can, at least in experimental, I mean, not in a lot. Lattice can
STFC-RAL-CR03 R61: have a different result. But what I wanted to say that.
STFC-RAL-CR03 R61: So this is the you. You write the same portal for nuance.
STFC-RAL-CR03 R61: and you have analogous purposes. So this is again the partner, interaction, etc.
STFC-RAL-CR03 R61: And another thing.
STFC-RAL-CR03 R61: Yes, the well, this is just to mention that the dark matter which is v plus has slightly bigger mass than the prime, but it's not bad, because V. Prime has a is a different guy in the case. But the Tilde is
STFC-RAL-CR03 R61: well, it's stable. The mass difference is very small. But oh, again, although there was a fine math, but it's driven by a group. Correct.
STFC-RAL-CR03 R61: Well, I will skip progression minus 2 discussion. But I I just want to say that
STFC-RAL-CR03 R61: if you believe that there is a whether or 5 or 4 Sigma discrepancy in data. You can actually use this model to explain this, you don't have to, because model predicts
STFC-RAL-CR03 R61: good writing, density and everything. But if you require that, this model also to explain. J, minus 2, you enter a very interesting region, and I'm going to some region of this model. Allow parameter space.
STFC-RAL-CR03 R61: So you need to calculate these diagrams, because, the anomous magnetic moment will be contributed by N. Primes. And this particles in the loop, just teachers and M. Primes. Heavy guys in the loops.
STFC-RAL-CR03 R61: And that matter well, this is that matter. And until this loop
STFC-RAL-CR03 R61: all this data must be calculated, and they behave like roughly like that.
STFC-RAL-CR03 R61: So this is the prefactor which is proportional to Muon, mass, squared
STFC-RAL-CR03 R61: times, gauge coupling without gauge, toppling square
STFC-RAL-CR03 R61: over mass of the the mass of dark matter. This is the mass of the Mvd. The mass of dark matter squared. So the smaller mass of dark matter, the bigger contribution.
STFC-RAL-CR03 R61: and Delta M is the mass split between M. Prime.
STFC-RAL-CR03 R61: And and so my split between these 2 terminals. The monthly between these 2 terminals is proportional to the 0.
STFC-RAL-CR03 R61: Okay? Good perfect. Yeah. So if I just look at
STFC-RAL-CR03 R61: the well the parameter space, if I require to describe a normally, then this is kind of region. This blue region of this edge describes anomaly quite well, so it requires. So
STFC-RAL-CR03 R61: if the company Gd is small, then it requires smaller muscle that matter. So basically along the diagonal according to to this formula. So it's proportional to Gd, and then versus proportional to
STFC-RAL-CR03 R61: master document. So those are just monitor this result.
STFC-RAL-CR03 R61: And another thing that direct detect for direct detection. You need to populate loop diagrams. Okay, you can believe me that. Well, we cross check this. We did this well, it actually was quite a lot of work.
STFC-RAL-CR03 R61: and we used well
STFC-RAL-CR03 R61: along cap and cal, cap and micro megas. We use also, and mandraft for collider searches.
STFC-RAL-CR03 R61: and in the end we end up with the this parameter space. So this is Master Documentta.
STFC-RAL-CR03 R61: and there's a decouplet.
STFC-RAL-CR03 R61: There are several regions which are good. Well,
STFC-RAL-CR03 R61: the green, blue are good colors. Means allow space.
STFC-RAL-CR03 R61: The red, orange, and purple means excluded space. We can see that genetic allowed space. It follows this line, which means that
STFC-RAL-CR03 R61: did they get toppling the well.
STFC-RAL-CR03 R61: the smaller already density. But so the bigger mass
STFC-RAL-CR03 R61: the more ready density, and then means that you need to do something to match the ready density to be just right.
STFC-RAL-CR03 R61: and the blue color, the the sign color. The light light blue sign cover
STFC-RAL-CR03 R61: allows to have even smaller coupling, because you're sitting on the resonant region, and I just want to kind of show that you, if you annihilate dark matter for the resonance it allows even smaller couplings.
STFC-RAL-CR03 R61: and there is some cool integration. Important region is with orange region which is Cmb. Constraints. I mentioned that the lighter dark matter, the more number density, the more number density, the more
STFC-RAL-CR03 R61: effect from that manipulation to Cmb, that's why, starting from certain point, orange color excludes quite a lot.
STFC-RAL-CR03 R61: and that's well. The the Cv constraints from indirect detection is quite low now to identify regions of the allowed bioretic density in direct detection.
STFC-RAL-CR03 R61: And
STFC-RAL-CR03 R61: well, this is another projection. This is mass of dark matter and mass of the Higgs. The dark heat. You can see that it's lies on the diagonal providing good density here, so that this is that's called resonant aggregation.
STFC-RAL-CR03 R61: And now I wanted to overlap. I would like to require good cosmology. So the good rally density.
STFC-RAL-CR03 R61: And this is you consistency with all directed experiment and G minus 2. It turns out that. Well, the only reason to survive is this, purple times.
STFC-RAL-CR03 R61: Why? Because the reliance Reli dancing division ghost
STFC-RAL-CR03 R61: along this diagonal, but G minus 2
STFC-RAL-CR03 R61: have a different slope, and they cross only in this corner.
STFC-RAL-CR03 R61: So it's you can see that dark matter now is is actually already, although the 10 G. But we didn't use collider constraints. If you use collider constraints, say in the in the typical yeah. So 1 min, 2 min. Pardon me, yeah, 1 min. If you use collider constraints, then you you actually exclude heavy document, heavy heavy thermal masks.
STFC-RAL-CR03 R61: Every manufacturer mass is excluded means that the small contribution in the loop. So in order to keep the loop contributing file.
STFC-RAL-CR03 R61: you need to decrease the mass of that matter to explain J minus 2. That's why, in the end, after the lighter constraints after, like we we use the
STFC-RAL-CR03 R61: you've got no minus a message.
STFC-RAL-CR03 R61: We end up with the relevant density. Sorry with the, with the documents to be below one Gb, it's very interesting. So we predict documents.
STFC-RAL-CR03 R61: If you like to explain G minus 2 to be below one G, which is like amazing. So it's very light document.
STFC-RAL-CR03 R61: And
STFC-RAL-CR03 R61: and this is related to like the last thing. This is just one of the last slide. I just want to show you that. Well, this scenario predicts not a lot of signatures. So if you have, and prime and kicks.
STFC-RAL-CR03 R61: and then fix the case to be primes and the prime because of my own portal, because this is the typical 6 new final state which, driven by initial 2 to 2 process in the I mean from from the beginning. So, like the branching out with other one, you can have up to well, 8, even 10 neurons in the final state.
STFC-RAL-CR03 R61: just by cascade, with with the branches of the other one.
STFC-RAL-CR03 R61: and one should also. Well, I kind of skip this, but you you can have observable rates at 300 inverse with this. So because the cross sections, or the order of, say, 5, 10 to the minus 2 centabar, including all branchings already. So it means that you could have a few events with the 6 laptops, etcetera.
STFC-RAL-CR03 R61: And this is the main message. So yes, if you produce M. Primes with the with only one TV, then you can have 6, 8 conductance whatever ferments in general, I want to kind of come back and say that
STFC-RAL-CR03 R61: this is what we only my own portal. If you have 2 portal, we can have
STFC-RAL-CR03 R61: 6, 8, and tops.
STFC-RAL-CR03 R61: If you have portal, you can have a
STFC-RAL-CR03 R61: same number of buttons, and very important thing that these kicks
STFC-RAL-CR03 R61: is has a similar mass as that matter, so this is very likely it will be boosted.
STFC-RAL-CR03 R61: so there will be boosted pair of, say, boosted pair of V primes, and again to new plus me minus etc. So bottom line is that we have several boosted pairs of mills and 2 ipt mills
STFC-RAL-CR03 R61: from this kind of prescription, which is maybe problematic because they will be coming in.
STFC-RAL-CR03 R61: I'm I'm coming to to the end. I just want to skip this. And well, it also because of S to that transition and also produce irritation waves. But I'm going to conclude, because that's likely keep some time for questions.
STFC-RAL-CR03 R61: So to decode that matter, we need signal. And first, st but we can close it, make a classification and prepare ourselves for discovery.
STFC-RAL-CR03 R61: Systematic classification is the key point in any searches and then interpretation.
STFC-RAL-CR03 R61: And when we broke that meta space
STFC-RAL-CR03 R61: well, there is a combination, of course, of different signatures, including displaying tracks, different electronic signatures, etcetera.
STFC-RAL-CR03 R61: But if you go beyond week kind of weekly coupled model, you can have even more surprises.
STFC-RAL-CR03 R61: more, I mean excitement. So say, for example, German portal to vector plus method.
STFC-RAL-CR03 R61: it's a model which already exist in the available and actually other people who use it. And it suggests it's represent itself. But in new class of model. So you you can suggest any portal we we can show example, the top portal and my own portal.
STFC-RAL-CR03 R61: and it, provides solution for dark matter and provides possible solution for flavor physics, because it was mentioned that. Okay, but it's flavor you. You can actually solve the flavor problem of this because we can solve maybe flavor problems in the physics. Well, which we observed recently some time ago.
STFC-RAL-CR03 R61: and
STFC-RAL-CR03 R61: It also also offers a multi permanent signatures
STFC-RAL-CR03 R61: and final statement is that the decoding the underly
STFC-RAL-CR03 R61: well, it requires joint efforts, experimentalists and theorists, and also machine learning approach because well approach to the database of models, database of signal signatures and link between them. We're trying to
STFC-RAL-CR03 R61: great and magnification, and many possible. So preparing ourselves to that method, discovery, which I hope will be soon. Well, I hope very much for this. Okay, thank you.
STFC-RAL-CR03 R61: Thank you very much. Sash for a great talk. And let's have a few questions. Yes, we have a
STFC-RAL-CR03 R61: some 900.
STFC-RAL-CR03 R61: So some of these
STFC-RAL-CR03 R61: signatures with multiple of the same object in the final state. I feel I have this feeling, but I don't
STFC-RAL-CR03 R61: no, that a lot of Susie searches have looked for these. Have you done any comparisons? Well, the the maximum number of letters we looked? I think it was 4 and more.
STFC-RAL-CR03 R61: but for moments that's considered. Here we we found that the main signature will be actually 6 6 miles, which provides the that's why this is kind of cross section and you need to multiply all branching to find the rate.
STFC-RAL-CR03 R61: But the this will be the leading one. Yeah. And it's not being looked at. That's why I'm bringing this kind of excitement to the entire experiment. But probably we can use some
STFC-RAL-CR03 R61: interpretation, because we can run it in. Well, we can check well, what's the security? But I assume that background probably would be very low for that.
STFC-RAL-CR03 R61: And so that's a question to you. And I'm very happy to discuss this
STFC-RAL-CR03 R61: and just a follow up question if you have. So so the way you've set it up, you can set it up. So you're from young. This is a new one.
STFC-RAL-CR03 R61: does it? Do you automatically get electrons, and Tau's no, no it's up to me to arrange portal. There will be no multi electron multitau. But if I create this portal related to electron.
STFC-RAL-CR03 R61: then it will be. But I need. I need to tell that you need to be a little bit careful when you create the portal of the 1st generation of ferment, because you need to. Well, there were strongly constraints from that time, but it is possible. But for for Tower there will be similar like feature, for probably there will be more constraints. I mean, I need to think about it
STFC-RAL-CR03 R61: if you so I'm still bothered by this this single article directly.
STFC-RAL-CR03 R61: Well, isn't I mean, there's running in the mass matrices. So don't you expect you mean like this right? Like single power? Right? Well, I know even the standard model. This is running in the mass matrices. So so the coupling to just one particle feels unnatural.
STFC-RAL-CR03 R61: True, true. But well, why people consider vector like tops. Right? So yes, it's we suggest. Okay, let's put this way. We suggest the class of models you. It's up to us now to put maybe several. So top and bottom.
STFC-RAL-CR03 R61: and and then we. This will have a form of metrics, because you have several flavors here. So yes, actually, this is the next step. This is this is just the 1st step which actually works.
STFC-RAL-CR03 R61: And maybe really one player is bit unnatural. I I agree with you. I mean it just kind of mechanism which is proof that it works. And then you can play more complicated thing to this.
STFC-RAL-CR03 R61: It's a good remark. I agree that
STFC-RAL-CR03 R61: small, like a class of models which you can develop.
STFC-RAL-CR03 R61: Well, let's take a question on Zoom from Chris.
Chris Damerell: Hello, Alex, very nice talk! Very interesting talk. I'm very ignorant on this, but I have a question that is in my mind, since there was a at Subur Saka's fest. There was a very nice talk from Copeland about the limits on the mass, and he indicated, and I haven't heard it contradicted. Since that there is a mass range
Chris Damerell: for primordial black holes, I mean, if they're too light, then they will have evaporated by now, and if they're too heavy they will have been seen by microlensing, but he has a range of something like the mass. Well, it's 10 to the 17 to 10 to the 21 grams, which is about the mass of Everest to about 10 to the 4th times the mass of Everest. And is that still open. I mean, I know that if it is
STFC-RAL-CR03 R61: The answer is, yes, it is absolutely open, and this is absolutely right. If the black hole, primordial black hole, is lighter than something, it will evaporate. And we are talking about. Indeed, this range you mentioned, I mean, if it's heavier than something, it will be fluid by. Micro. So this range. 3 orders of magnitude is there? So it's it's about 3 orders
Chris Damerell: It's very interesting, because the you know the Lsst or Vera Rubin telescope is should it's been so much delayed. But it should get its 1st light this year, and that is one which I think has the problem with detecting. It is that you can use the
Chris Damerell: gravitational lensing from stars in a large Magellanic cloud, but they're so dense that there's often a crowded field problem, and it's hoped that the room and telescope will be all right for that, so we may get the answer on that one within the next couple of years. If that's really the case.
STFC-RAL-CR03 R61: Was talking about that matter from the perspective of particles. Right? So. But yes, they, the primorial black hole in this narrow mass range still allow. Well, we're talking about the primordial black hole which are 100% can contribute to ray density. And this is true. That is possible
Chris Damerell: Thank you very much.
STFC-RAL-CR03 R61: Yeah, just was divided by particle physicist. Positively.
STFC-RAL-CR03 R61: Thank you, Chris, any questions here?
STFC-RAL-CR03 R61: Actually, yeah, it's time for lunch. So let's stop here. And yeah, we'll have lunch with
