Ivana Hristova: No Barbara yeah can you hear me well.
Ivana Hristova: Oh yes.
Barbara Clerbaux: Yes, thank you very much for this.
Barbara Clerbaux: for inviting me to be disgusted not.
Barbara Clerbaux: Clear for me to do with them.
Barbara Clerbaux: Your support a nice organization.
Barbara Clerbaux: gang.
Barbara Clerbaux: So yes, I will present to to the.
Barbara Clerbaux: What I call the cms physics highlight and i'll be really focused on his end results.
Barbara Clerbaux: So this is the plan of the Center maybe it's a bit too ambitious for some of the other side.
Barbara Clerbaux: And on the time but, basically, I wanted to present to a first part on stand out more than the measurements mainly use a quote from fees, because we had a nice job.
Barbara Clerbaux: Of course, also about on searches.
Barbara Clerbaux: Here we presented the latest covers on my grandma also to win and be obedient as a service that keeps production.
Barbara Clerbaux: And then really selected two topics for that access on.
Barbara Clerbaux: Okay, before we give a very short motivation and.
Barbara Clerbaux: And again.
Barbara Clerbaux: This is from the plan for the for the event.
Ivana Hristova: hello, Barbara before we start, can you there is a bit of a background noise.
Yes.
Ivana Hristova: Can you can we try something.
Ivana Hristova: To see how we speak to the microphone.
Ivana Hristova: Yes.
Ivana Hristova: yeah we see something like like a movement or when you.
Ivana Hristova: There is a background noise that's picked up by the microphone so it's not very clear.
Barbara Clerbaux: We wanted to remove the microphone.
Barbara Clerbaux: Is the fun of my computer.
Barbara Clerbaux: We move it.
Barbara Clerbaux: Better like this.
Ivana Hristova: Maybe it's a bit better.
Barbara Clerbaux: Yes, okay sorry to speak loudly like this it's okay.
Ivana Hristova: Yes, and try to speak louder.
Ivana Hristova: that's fine okay i'll do my best.
Barbara Clerbaux: Okay, thank you, so this was the plan of listener.
Barbara Clerbaux: yeah okay so for the motivation as, as you know, the standard model is is performing very, very well up to know.
Barbara Clerbaux: We have discovered the each Muslims can vote on which was a very important step, the completion of the standard model but, but we still have many questions that remain in explained by the standout moment.
Barbara Clerbaux: And just the one that I least a very important observation, for example, what's the healing the very nature of the matter also understand the matter it matters symmetry.
Barbara Clerbaux: and include that in the Madison the modern these three points are very important and.
Barbara Clerbaux: not satisfactory or describe know by the standard model, but this is really important issues that we have to try to understand, no and there are a lot of other questions that I also tied to these are some of them were we'd like to have.
Barbara Clerbaux: explanation or hint of.
Barbara Clerbaux: of ID how to solve all those problems so it's a very challenging time and last event I said at the beginning, is to have great moment to look at the full hundred to nfc data set and to search for him it's often physics, looking at high energy efficiency, we are really.
Barbara Clerbaux: high energy machine so it's never fun to, we are not running after 13 TV in the cotton cotton sent off my system.
Barbara Clerbaux: But also thanks to the large data sets, we are also going to have prestige, unquote mustn't exceed a certain problem machine but it's really amazing hope or precise you can you can go know this this machine.
Barbara Clerbaux: So just to remind you, if you're working under the Steve if you are not to explain you what the difference between one and two.
Barbara Clerbaux: So you see here in 2010 11 and 12, this is the data taking by different one So you see the total integrated military here, which is.
Barbara Clerbaux: About 30 that's going to bomb and then after the shutdown you see that, then they went to the Vatican 2015 1617 and 18 and you see how large the data we have taken during the stereo and.
Barbara Clerbaux: A whole big data sets we have not.
Barbara Clerbaux: So you see here the idiocy delivered, so what the machine deliver to.
Barbara Clerbaux: The experiments and what cms has recorded.
Barbara Clerbaux: So in this in this presentation, I will show you mainly results, using the full ubuntu data set.
Barbara Clerbaux: But for cms mainly we use, not the 2015 data, because it was a very soft amount of data, in particular, we have also problem with a magnet at this time.
Barbara Clerbaux: So the good data that we can use are quite small so In fact we use the data set thinking 2016 17 and 18, as you can see here, and these amounts to a total.
Barbara Clerbaux: Of about 137 that's comfortable for 140 depending on which is a lot of people So you see, this is a very large amount of data set that we can use now.
Barbara Clerbaux: Of course, you have to combine three years of data so it's it's it's challenging and a lot of work to do these amendments, if you have a high university or high instantaneous university, this means also that we have large pilot so pilot she's the number of.
Barbara Clerbaux: of interaction that you have a bunch costume and you see that during control typically it was.
Barbara Clerbaux: Around 3030 3735 in the action that you have to put on bottom being mentioned in costume so it's a it's a really large number of interaction, so you have to mitigate this.
Barbara Clerbaux: This additional interaction to the one that you are interested in, but we have a lot of techniques to do that and I will not discuss that in this seminar.
Barbara Clerbaux: So for the for the data taking so, as you know, it's it's capital to this to have very.
Barbara Clerbaux: Very good triggers for the one to use a standard trigger as as it was for the for the hunt one, it means using.
Barbara Clerbaux: For example, high PT leptons or a PT jets in the in the detector using texting and also using event with higher consciousness missing tons of energy met.
Barbara Clerbaux: Those are the standard trigger but we develop also other kind of trigger for them to be back in two years, we store the data which are lower trigger question.
Barbara Clerbaux: And we delay the processing of these data we process in fact this data, doing the long run down that we have now.
Barbara Clerbaux: And with this be packing a trigger we have about 10 billion event and hitch in unbiased be the case, so this is a very interesting interesting data set that we can use to.
Barbara Clerbaux: To to to to analyze and to do be physics, so, as you know, this was the design, in particular, due to the anomaly that we're seeing in the leptin universality in the in the English CB.
Barbara Clerbaux: hazards so now this data set has been processed and we are analyzing it, but I will not present hazards on this, because they are not had yet.
Barbara Clerbaux: another kind of triggers that we are using is discouraging where we try to lower the pediatrician, for example, to to to study jet digest has announced things like this at lower PT.
Barbara Clerbaux: So we lower the PT session and the mass election, and we do that, thanks to addiction, of the even size.
Barbara Clerbaux: Due to physics object for constructed at the high level trigger so we do not use a full construction.
Barbara Clerbaux: You know this is a trick, that is also working quite well for some of the apology for some of the analysis, I will not present those hurdles, because they are not very efficient and I focus on only on last last year has basically in this year.
Barbara Clerbaux: We have also special trigger trigger.
Barbara Clerbaux: For special one in three years and not by the triggers, of course.
Barbara Clerbaux: So, before going to the results, I would like to mention that cms and certainly atlas as well, I spent a lot of time and effort to have a full on to consistently processing with final calibration what we call the legacy samples.
Barbara Clerbaux: With the final alignment improvement in the simulation of the detector condition, etc, so he I give you some some example.
Barbara Clerbaux: For example, you will see the second bullet new template fitting technique for constructing the amplitude in the decal, so this is a new technique holiday to the eagle signal, so the electro magnetic kilometer of cms.
Barbara Clerbaux: And if you're interested I put the reference next to it and we're also improvement in legacy electron photon reconstruction.
Barbara Clerbaux: And you can see here in the in this broad below the input improvement that we have for this final legacy sample compared to the end of year.
Barbara Clerbaux: calibration or and the fear, but he processing, if you want So here we realign we calibrate oldest detector component, we have improved the simulation description.
Barbara Clerbaux: We have updated he can transparency correction more granular calibration of the crystal etc, so if you are interested, you have all the details in the.
Barbara Clerbaux: In the paper there that has been submitted to two genes and you can see few plots that I selected from from this analysis.
Barbara Clerbaux: And particular if you look at the lower left plot it's really nice to meet you the data among the Gala agreement for the electron fi distribution, so you expect that this this distribution is basically flat.
Barbara Clerbaux: it's not flood, because you have some effects from from the detector and you can see how well the the simulation this is for tyrion events or does he pick.
Barbara Clerbaux: How well the simulation is kind of data, the shaping fire, so this is really impressive and the other plot show you the the improvement of, for example, the energy or construction or the Damascus ocean or the or the energy scale when you compare.
Barbara Clerbaux: The end of the year Fico hear no evil white eagle and the legacy also you can compare the Fed and the blue.
Barbara Clerbaux: And you see the improvement and the efficiency that we are teaching know for the electronic construction for the mass again, you see the proof on here.
Barbara Clerbaux: The head going know to to the Green and you see that the mask resolution depending on on each is typically from one to two bit more than 2%.
Barbara Clerbaux: And you have here the analysis scale and you can see how good we have the energy scale know it's really a department level.
Barbara Clerbaux: So it's it's amazing, and this is important, of course, when we will discuss the issue gamma gamma analysis, we need to have very good mass resolution to extract high sensitivity for the higgs.
Barbara Clerbaux: Okay, so other things that we have platform is to improve the tools, in particular, going from multivariate analysis tool to deep neural network, and you can see just few example of tools for object reconstruction that we have been developed in cms we have developed a new tool Upton ID.
Barbara Clerbaux: Which is called deep to so it's a new multi class.
Barbara Clerbaux: Integration algorithm, which is based on a conversation and deep neural network, so it combines information from high level or constricted to.
Barbara Clerbaux: Together with low level information from the inner psyche or the cat meter and the neon detectors and you can see, the improvement of the tool compared to the previous mva.
Barbara Clerbaux: To ID that we are using before so in giving an head and you see the new so.
Barbara Clerbaux: Deep that you are, that you are not using for the analysis and this show you what this show you the JET miss ID credibility.
Barbara Clerbaux: As function of the assumption of the efficiency of the toy ID so basically you want to have a high efficiency and a low just miss miss miss it quality and you see the improvement between the two tours.
Barbara Clerbaux: The same here and not for the tool, but for the be tagging no I got it So you see this in the same plot, so the Messiah the Community as a function of the DJ efficiency.
Barbara Clerbaux: You see how the new angle hitman which is called deep jet is improving, compared to the previous one in the height, so you compare the blue line and and the headline and the last one.
Barbara Clerbaux: Okay, this is just two examples of of new development for the tool that that are using the analysis, so this is the very.
Barbara Clerbaux: Common propaganda plot for the for the communication I think it's interesting to see that cms and atlas as well, the same is really multi multi.
Barbara Clerbaux: experiment, if you want with with large working who's working on very large number of analysis and you can see that the exotic hope it's.
Barbara Clerbaux: it's publishing a lot of paper, and this, because we really want to try to have hint of in physics, of course, then you have the standard model and the higgs scope having also a lot of presents followed by supersymmetry and then standard model of physics and so on.
Barbara Clerbaux: So in this in this talk, I will really focus on new publication so.
Barbara Clerbaux: Preliminary results or public published results in 2020 or 21 and.
Barbara Clerbaux: Many all of them using at the full data set.
Barbara Clerbaux: And of course it's on your selection, so I just select the one that I, I feel that was very involved.
Barbara Clerbaux: So let's start with the standard model measurements support from your physics, so I cannot resist to show you this again this beautiful plots showing the production costs section.
Barbara Clerbaux: and measured in bigger band as a function of metrics what the X axis is different processes on the standard model, so we start.
Barbara Clerbaux: On the left side with the production of w off of is, these are these are electric cars section so it's already local section are clearly compared to the QC the one.
Barbara Clerbaux: That you see that it's the highest the highest one in this blood and you see the three colors can respond to the three energy and you can't hear something that you can use 3217 TV to it TV and living with certain TV so fundamental.
Barbara Clerbaux: And the different costs section here is is, for example, he has w plus one jet prestigious prestigious is for drugs, you see how precise, we can measure, now the Cross section, and the same for the Z.
Barbara Clerbaux: Then you have the measurement of the diapers on for Section so w photon photon www dmz and then here, you see the Vb production those results are in last two words by a few slides on these are very nice, I mean.
Barbara Clerbaux: I will also speak about to electronic prediction here of gamma w press to jet and easy just to jet and you see that this is a fairly fairly low cost section that we are no.
Barbara Clerbaux: measurements, and this is actually the lowest some that mother measure only costs section that we are known for being.
Barbara Clerbaux: So we are testing the standard model to their processes, we also look at the financial prediction, and this is possible, not in the accident, reconstruction and calculation performance that I just mentioned, just before.
Barbara Clerbaux: So let's start with the production of the value the value pair so WW production was already done before, but here what we would like to do is the measurement of the polis same sign WW pass.
Barbara Clerbaux: So this measurement is the victim was on scattering process or the business process and it's very important to test the electronic symmetry breaking in the sector in the sun that modern.
Barbara Clerbaux: and also with this we can search for production construction modification as a hint of bs and physics, for example, if you have additional higgs boson.
Barbara Clerbaux: And someone.
Barbara Clerbaux: So to select, this is a this this process, we have to attack.
Barbara Clerbaux: This event searching for that selecting to energetic for objects.
Barbara Clerbaux: We have large environment mass and last up to the happy dt.
Barbara Clerbaux: distance between the two jet's.
Barbara Clerbaux: We use control agents to constrain the standard model back on which I list here and abilities are boosted decision tree is used for the signal selection and and the backlash action so two separate signal come on back home.
Barbara Clerbaux: can see here the using a simulation the distribution of the the as the middle angle between the two left on in the final state and you see that it's different.
Barbara Clerbaux: For the Cross section, where you have the w which is launched in I apologize to WB non-genetic polite this isn't in head.
Barbara Clerbaux: Or the two w being tons of Sally polis is in black and you see that you have Defense hunker down distribution.
Barbara Clerbaux: So of course this is very small class sections, so it was not possible to measure the three contribution, so the ll empty and the TTS contributions separately, so what we have better perform is a simultaneous measurement.
Barbara Clerbaux: Of the ll and the ti X where X can be tons and tons of Apps on on getting.
Barbara Clerbaux: This is one possibility or another moment where we where we skip ahead, the ttc at this time, so we target the TT and the empty, the story where it's can be T or.
Barbara Clerbaux: And we use, of course, the event kinematic properties to extract the values contributions.
Barbara Clerbaux: So you see here the results of the bdd score in the boss both cases so first, for example, here in the Left plot, you want to differentiate the longitudinally polis longitudinally by the highs.
Barbara Clerbaux: With the other with the other two, so you train your vtt participation and in the height plot you do the opposite.
Barbara Clerbaux: When you target the TT cross section.
Barbara Clerbaux: And the ll cool section is very, very small so it's a very challenging and you see here the results of the measure of costs section in the table.
Barbara Clerbaux: In the first case, when you separate the l amp D So you see that the end is very small, and is basically compatible to do, and then you have the other option when try to measure the transverse contrast one and you see the numbering and.
Barbara Clerbaux: So direct toby production, where you have at least one longitudinally for the highest value has been measured and, if you look at the number, you will see that its measured with a 2.3 Sigma.
Barbara Clerbaux: Here we have a bit of a deficit because we would expect when we should expect the trip on one Sigma.
Barbara Clerbaux: And we can put a limit on the production of.
Barbara Clerbaux: Cross section at about one point 17% about.
Barbara Clerbaux: So I think this is very interesting and important reserves that had been published just last year.
Barbara Clerbaux: Another.
Barbara Clerbaux: movie was on production measurement that is very recent electric production of a w a photon plus to jet So you see the head of venn diagram here on the top.
Barbara Clerbaux: So what do we have we select one lipton electron of me on one for them, so the leptin comes from the key of the of the w.
Barbara Clerbaux: And a two jet's with large opportunity separation and large environment mass as as before, and the motherhood in balance in pity because we have a w so we have any cleaner in the finance it.
Barbara Clerbaux: Here you can see, the distribution of the event for the inbound mass of the w photon.
Barbara Clerbaux: This is for the 2016 data set, but this presence of has been conveyed to the one one and you observe signal significance when it's combined with on one hazards is of 5.3 Sigma, so this is not really the first observation of this.
Barbara Clerbaux: w photon process.
Barbara Clerbaux: And cms and you can see, also, that you can put constraints in the anomaly squatters gates coupling by this analysis is this process, and you have an example in the proton how the distribution would like would look like in case of this and amanda aquatic gauge company.
Barbara Clerbaux: The other very, very low cost section that are speaking about before the zebras to jets and activate production.
Barbara Clerbaux: Here we have made the analysis, using the fully lipton financed it for the CD case, so we have four leptons either electrons or million it's a Vb vpn like a production, you can see here the diagram on the height side.
Barbara Clerbaux: And you have here the plot on the left, where you see the full dataset results number of event as function of the environment of the four lipton.
Barbara Clerbaux: And you can see, the different on bag on and the contribution that you expect from the electronic process Easyjet, which is the pink one here, which is very, very small cross section.
Barbara Clerbaux: Of the observed and you expect the significance of the signal is for Sigma for the observed and 3.5 for the expected, so this is really the first evidence of this process.
Barbara Clerbaux: We have used to discriminate and metrics.
Barbara Clerbaux: Discrimination based on metrics element likely oppose, which is good and Mila in the same as the one using the hits in for lipton analysis.
Barbara Clerbaux: And this is the results of the costs section So you see the section that is measured is about the whole point.
Barbara Clerbaux: For them to banish is very, very low cost section.
Barbara Clerbaux: And again using the standard model, a measurement you can also constrain anomalous coupling this case quality gauge coupling and you see how it would look like such a signal in this for electronic by in mascot.
Barbara Clerbaux: So coming to the V V production now, so this is also very, very nice results, so we have different production mechanism accessing different.
Barbara Clerbaux: processes, you have the triple H copying in this showing this diagram, you have the vv H sculpting here, and you have the quality, which comes in here.
Barbara Clerbaux: So when we say VI VI VI, it can it covers the three w production w w.
Barbara Clerbaux: w Z and Z this class sessions very, very small.
Barbara Clerbaux: And, and so I would like to murder this process, the standard model, a process but also it's very sensitive to new particles connecting to the vector verizon, as you can see here on the on the diagram in the in the head square or model modifying the standard medical things.
Barbara Clerbaux: So the finite state that we look, is the fully fully electronic one or the same saying leptin so we have financed it from two to six lipton we have different channels that have been combined at the end.
Barbara Clerbaux: Data driven back on estimation from control the region and the main uncertainty in this analysis, come from the bag on estimation.
Barbara Clerbaux: To parallel analysis has been closed, one could be, and when we look at least and have been compared compared you see an example of one of the.
Barbara Clerbaux: DVD production, this is targeting the wwdc going in for lipton so you have one Z going into leptin pair and the two w going to limit on neutrino so you have indeed for leptons in the final state and missing tons best analogy.
Barbara Clerbaux: Here you can see the results so it's the number of event for all the category that has been analyzed you see here on the bottom, first the same sign developed on So this is the category where you have.
Barbara Clerbaux: To leptons, then you have the three leptons getting away and then you have the full leptons and and the height side you have five leptons and the six items.
Barbara Clerbaux: And you see the tables on signals that you expect from it stand up Mullen in my head www and you can see that, for example in the tight lipped on what you expect to see this is.
Barbara Clerbaux: This process, you see clearly.
Barbara Clerbaux: The contribution from the individuals.
Barbara Clerbaux: And each of these you have subcategory depending on the left on save or depending with you have a jet etc.
Barbara Clerbaux: And you can clearly see that we, we see the signal we see the event, and we can measure the signals things, this is the new parameter here, and you have the results for the WW measurements here.
Barbara Clerbaux: Is.
Barbara Clerbaux: For the WW Z for the wcc foot is busy here, we have no no measurements that and you see the combination of the channels.
Barbara Clerbaux: are here with a new value of 1.02 plus or minus about the hope 120 2526.
Barbara Clerbaux: So, the results are consistent with the standard model and.
Barbara Clerbaux: And here, you have also the measurement of the cross section, if you if you want.
Barbara Clerbaux: He actually you were even display of one of this event candidate, this is for the wwe going to see in for leptin.
Barbara Clerbaux: You see, to me on here compatible with going from from the zebras on, so the me on two and three opposite charge.
Barbara Clerbaux: And then you'll see a million and the next one.
Barbara Clerbaux: which may come from the first w lucky and in the second debate.
Barbara Clerbaux: I give your so here a table of the significance of the of the process for all the different process and for the combination and you see that if we combine those gentlemen, we.
Barbara Clerbaux: hide that we can have more than five Sydney So this is the first observation of the politician and cms and you will see that we also have some evidence of individual Shannon nobody w wm w w because we have more than than three signal.
Barbara Clerbaux: So if I come back to my similar a plot to see that these three measurement are the one that are here for DVD Annapolis of presenting it to win it, but I highlighted through the second.
Barbara Clerbaux: So this is very nice because very few of process.
Barbara Clerbaux: really try to understand the.
Barbara Clerbaux: The important part of the of the standard model and also.
Barbara Clerbaux: can provide think of new Felix if we have additional.
Barbara Clerbaux: For example, these words on audition and interaction.
Barbara Clerbaux: So another section that I wanted to show as well.
Barbara Clerbaux: The topic or section plus champ addiction to, so this is a very difficult and challenging analysis, where you try to maturity tobacco section with to.
Barbara Clerbaux: charms Assisi mafia in the finance did we did this measurement the dialect and the kitchen of the top.
Barbara Clerbaux: And, of course, the challenge is to tag the charm jets and for this we developed.
Barbara Clerbaux: The entity that champ tiger.
Barbara Clerbaux: That can distinguish.
Barbara Clerbaux: The ttc signal that you're looking for to the city db and TT TT lights flavor jet processes.
Barbara Clerbaux: The template statins method is used and it's based on the output of the learner to classify your train to identify different signal category is fine by the flavor of the additional jet so it's about hitting the CC bb bb bb and light, the object.
Barbara Clerbaux: And you can see, the number of vent as a function of the.
Barbara Clerbaux: score here.
Barbara Clerbaux: And you see the contribution of TT CC in yellow.
Barbara Clerbaux: Together with the TV and the TT light light flavor.
Barbara Clerbaux: So as soon as you go to the to the right side you see that you enhance your contribution to the system.
Barbara Clerbaux: So this is this analysis is really the first measurement of this process or 20 plus the production, construction and also we measure the air see ratio, which is the cost section ratio of T T plus C to D best lightweight objects.
Barbara Clerbaux: And the same with the be strategically bb over the ttp chet chet you see the results of the cross section in the table here.
Barbara Clerbaux: And you can see, it also visually in this plot, or you see the construction measured, for example on the on the spot on the top left one it's the ttc Barker section in the X axis and the y axis is the TT bb bb cross section.
Barbara Clerbaux: You saw the measurement you see the measurement in black with the one Sigma Sigma arrow and you see the expectation from the standard model.
Barbara Clerbaux: And you see that in one measurement we are a bit of this measurement for air B.
Barbara Clerbaux: We have a deviation of about 2.5 Sigma se it's fine.
Barbara Clerbaux: So, this would be interesting to follow in the future and to see how this small deviation is.
Barbara Clerbaux: Staying with more statistic owner, so no I switched to each other's for the results of the.
Barbara Clerbaux: Of the measurement in the IT sector, so the scallop sector.
Barbara Clerbaux: Are, I will start with the H mass murderer man, which I found call with amazing how precisely we can measure now this this parameter.
Barbara Clerbaux: So for this, we have an updated analysis from cms for age to gamma gamma I put here the reference or within the slides So here we use a refined the text of calibration and new analysis technique.
Barbara Clerbaux: It is based on the 2016 data set only.
Barbara Clerbaux: But we have also combination with the one one, this is the cms and he has also, you can see the results on the measurement of the mass of the of the higgs for the one and or the gamma gamma in the zte channel separately and combine and then you see the new measurement.
Barbara Clerbaux: Using the 2016.
Barbara Clerbaux: Data set with very.
Barbara Clerbaux: He find calibration and for with a Z and the combination and then you see know the final combination of one one and.
Barbara Clerbaux: 2016 year of the hunter and you'll see now that the measurement is 125 point 38 G for the for the higgs mass plus or minus the hop on 14, and this is the total arrow the statistical arrow is the whole point 11.
Barbara Clerbaux: So it's here, I think, is the most precise measurement that we have of the of the ah nice to me.
Barbara Clerbaux: So this was for the mass What about the coupling, in particular the coupling to famines so to matter particles.
Barbara Clerbaux: So, as you know, the age copying, to the third generation has been observed, and he gained to leptin was observing summer 2017, and this was a very important wizards.
Barbara Clerbaux: The Association production we stop quarks hicks stop class was also observed in spring 2018 the decay, to the bottom clock.
Barbara Clerbaux: In summer 2018 and nobody's, for this is for the copying, to the third generation Now the challenge is to mirror the copying, to the second generation and you see that this is very challenging for each to see see.
Barbara Clerbaux: Here we have again to tack charm quad so it's very difficult, especially because we have a very, very large back home from which to be the bar.
Barbara Clerbaux: So see tagging is critical, there has been some analysis.
Barbara Clerbaux: Come winter 2019 and cms will not discuss it, but if you're interested, you can look at this paper, and you can see that we are probing new value inadequate what 70 see the observe the expected to separate 30 time to stand up money.
Barbara Clerbaux: So this is for htc, but we have also analyze the possibility to to measure the age to new new and, as you know, cms has.
Barbara Clerbaux: holly's the new users.
Barbara Clerbaux: shipped 2020 so last summer, using the full amount to data.
Barbara Clerbaux: So, and this is what I will present know, so this is the new results of the analysis of each to new in cms so it's a very, very good, as you know, the benching infection is less than 10 to the minus four to two tenths minus four and we have a large irreducible back from from Thailand process.
Barbara Clerbaux: So we had to study the for production side channel to have the full sensitivity, so the glue glue ah, the VHF channel, you can see, the two plates on the on the left, but also the dth production mode and gh so the production of of weeks with a w or is this the person.
Barbara Clerbaux: The best sensitivity come from the from the to channel here, so the the glue glue age and the vpn they have the higher cross section, and the best entity come from them, yet, because you can reduce the large background, thanks to the fortunate requirement.
Barbara Clerbaux: So we're not coming to the detail of the analysis, but you can see here the distribution of the vtt output for the various categories.
Barbara Clerbaux: here for the glue glue age output, you see the vertical line clear line are the values category how the analysis is divided in in very clean in the bit less clean category, etc.
Barbara Clerbaux: You see, the daily and contribution in yellow and you see the bbs contribution in in the hat the red line and the guru he in the.
Barbara Clerbaux: end the black line.
Barbara Clerbaux: So this is a nice candidate for H two new new and you see the 2 million here, since a candidate event in the cms detector.
Barbara Clerbaux: You see here the distribution of the mass of the Damien systems in there, and most of the time Ian between one and 10 and 150 you see the data, and this is for the VP of category only, which is quite.
Barbara Clerbaux: which has a good sensitivity and you see in the blue the contribution from the each community event and you see on the ratio, or when you do the data minus the background How did this contribution appears it's a small contribution, but it's it's clearly visible.
Barbara Clerbaux: And on the high side, you have the finance distribution of all the categories or the signal over the kidnappers back home awaited even distribution, using all the categories and again on the bottom purchase data minus backhand and the smoke signal that we see here.
Barbara Clerbaux: So from this, you can extract the best fit new value.
Barbara Clerbaux: For the four categories here and for the combination, so the combination is given here it's one point 19 plus or minus 0.4.
Barbara Clerbaux: You can see here.
Barbara Clerbaux: copy Kelly, the new VP of HR as a function of the New Jersey, he did TT TT he compare the measurement compared to the standard models so there's there is a good agreement.
Barbara Clerbaux: And the significance of this measurement is this thing, and if you want is that just three Sigma we expect at 2.5 so we have been a bit lucky we have a bit of an access, and the second chances is just twisted man.
Barbara Clerbaux: Okay, here I put.
Barbara Clerbaux: The coupling.
Barbara Clerbaux: For values particular as a function of the Vatican master this is a very famous products that you have seen before, and it's a very beautiful clothes, because you can see all the coupling.
Barbara Clerbaux: Is following the straight line if you want expected from the standard model so he is key fob square who don't have TV if it is a company into a Muslim So you see here the measurement for the top for the Z and the w the bottom, the toe and know we have in addition.
Barbara Clerbaux: The measurement for the for the hicks to Mumia coupling, so this is a very amazing hazards you see how are low, of course, this.
Barbara Clerbaux: Is the sculpting and that know we are able to to measure this point of failure and Nice achievement and what we can do also we can do a fit.
Barbara Clerbaux: For the sixth us couplings thanks modifier so the six that are hidden here 123456 as a function of the trafficking mass and you see that the best fit is given here 127 plus or minus zero point 22 so it's pretty compatible with one.
Barbara Clerbaux: Okay, so this is it for the H2 new age to gamma gamma so I show you before the very precise mass measurement but here we have also analyze the full age to gamma gamma full went to data set.
Barbara Clerbaux: And you can see here the data distribution.
Barbara Clerbaux: subtracted with the vagabond on the bottom, you see the clear pin that we have no is to gamma gamma is the full data sets amazing.
Barbara Clerbaux: The value of new that is extracted from this analysis is 1.03 plus or minus about the upon 10, so we are predicting precise measurement here and competitive and this one so compatible with the standard model.
Barbara Clerbaux: We also developed reservist according to the simplified template cross-section scheme, which is has been developed by theories and cms an atlas people to seamlessly minimize the experimental and the theory.
Barbara Clerbaux: And the theory uncertainties on the edge construction measurements, so the idea is to define exclusive judicial region.
Barbara Clerbaux: By production mode that be some observable and said, etc, that document within cms at lesson and the opposition, so the game can be contacted and they can be used efficiently.
Barbara Clerbaux: So you can see here the hazards of of this but i'm not go into the details so again, and I did also for the age to total this time using the full data set.
Barbara Clerbaux: again here the final state.
Barbara Clerbaux: that are used as the one has all the possible one so at the honeycomb K or Atlantic to the key and the key or the final state.
Barbara Clerbaux: So the deep neural network, the two under him that I was speaking at the beginning, is using this analysis to take the advantage to decay.
Barbara Clerbaux: And you can see here the update preserved so the distribution of events as function of the environment, mass of the total system and the zoom aren't the peak of the higgs boson and you can clearly see know that we have failure nice number of events.
Barbara Clerbaux: is to to to hear the new value it's a bit low, so we have a new value of 0.85.
Barbara Clerbaux: plus or minus the upon the 2011 here.
Barbara Clerbaux: And for this analysis will use the Grigori pollution pollution reserves rule here for the new value, but also the PDF one, so that you can age.
Barbara Clerbaux: Which is here, in the middle, so in the average citizen in the plot Point five.
Barbara Clerbaux: Okay, he you see an example of the different categories in this PDF.
Barbara Clerbaux: PDF production mode for each and you see here.
Barbara Clerbaux: that the contribution of is to go to which has been scaled to the new value that is observing the data, so the whole quantified.
Barbara Clerbaux: This is again a productivity done but, again in this framework of simplified templates section, you can see.
Barbara Clerbaux: mature audience specific occasion of the faces.
Barbara Clerbaux: Okay, so the last analysis, I wanted to talk about concerning the heat sector is the booster each to be so, this is also nice analysis, where we call pipe the tea leaves.
Barbara Clerbaux: As support for new physics, indeed, if you have a physics in the loop or a new interaction, you can see, affect.
Barbara Clerbaux: US process.
Barbara Clerbaux: So the idea here is that the bottom quark have boosted, and then, as they are really highly boost their immediate constructed in a single lot pages checks, as you can see.
Barbara Clerbaux: The cloud, and so we developed for this analysis as a dedicated deep learning algorithms which is called deep web tag on.
Barbara Clerbaux: that's used as an input to tax and the second ethics.
Barbara Clerbaux: And also, this is done through combat at the end, the final layer is expected input in the idea is to separate between the heat jets that would look like this substructure off of the subject, inside and eliminate this game of the energy from the sun projects coming from the.
Barbara Clerbaux: sky.
Barbara Clerbaux: And you see this deep.
Barbara Clerbaux: Deep neural net the deep learning algorithms that is dedicated to the stand up the energy you see how it can cost compared to the previous validity to that class was before.
Barbara Clerbaux: If you if you want to stay the same db has been studying efficiency, you see that know the new tools.
Barbara Clerbaux: As a better baton detection, a factor of 2.5 yeah and if you still have the same.
Barbara Clerbaux: To something amiss it probability and you see that the new tool here as a better signal efficiency of about 145.
Barbara Clerbaux: So this tool is used for this analysis and you can see the results here is the number of event as a function of the mass of this.
Barbara Clerbaux: bb large now objet.
Barbara Clerbaux: You see, the dotted line in the contribution from the PCP backhand you see nicely, also in the doctor said this, the Z contributions, easy to be speaking to the Mafia.
Barbara Clerbaux: And then you have the contribution of each to be the law that isn't in here so it's a small contribution.
Barbara Clerbaux: And here, and here the new value as we take them to 2.7, this is the one we are serving to do SEC a bit of an excess compared to the standard moment So you see here that the new value and not sorry, you see here the new value.
Barbara Clerbaux: And here the new value has been separated values being TT for the he goes on, so i'm looking at to hype up and you see that the small access benefit of maybe a trance entity, so this will be interesting to see in the free tutorials model quite good.
Barbara Clerbaux: and accessible at one phone signal and go to the stand up.
Barbara Clerbaux: And you see that it's it's mainly a type a type.
Barbara Clerbaux: Okay, so I go to the last.
Barbara Clerbaux: Time.
Barbara Clerbaux: I am a bit slow, so I will go a bit fast and maybe skip through of the of the search and we have order the happiness in this life.
Barbara Clerbaux: That, I want to go to this one, because this you search for the physics in the dialect on finance, this is the one we found was that helpful.
Barbara Clerbaux: Since a long, long time for things from one and 411 set up to collect from how the methodology of this analysis and we performed it together on different one and number two, and this is some older leaders have.
Barbara Clerbaux: Using the full of them to data sets So this is the mass spec tone for the day, electronics, or you select event, with two.
Barbara Clerbaux: Is related electron or to irritate me on the on the on the heights you compute the environment mass an even distribution, you see the Nice zte.
Barbara Clerbaux: mighty one, and then you see the large TV or up to 3.5 TV, where we have our last event, and this is where we are looking for them for new features for new heavens.
Barbara Clerbaux: And so we search for heavy resonances.
Barbara Clerbaux: The.
Barbara Clerbaux: New and we can put limits on values, modern, for example, values pin one, the prime model from from, for example, hunting theory, you can also put you down speaking tongues.
Barbara Clerbaux: From a single mothers and mothers.
Barbara Clerbaux: By mentioned.
Barbara Clerbaux: As well as in when we talk between the mother and the class and then the death metal particles of savages show you know.
Barbara Clerbaux: So this is the result of this analysis to see the foot on the left.
Barbara Clerbaux: Is the unit as a function of the math and you can see the Cross section for standard model SMC crimes, and this is a heavy hand me the same cockiness of dizziness and modern.
Barbara Clerbaux: Music for this game is a benchmark and again, we see that the limit is up to five on TV, where is the crime.
Barbara Clerbaux: And father, mother coming from.
Barbara Clerbaux: From the pinhead music and copy.
Barbara Clerbaux: To the feminine understand the music, you see, also the new it in case of.
Barbara Clerbaux: candle central models and this affects how I mentioned modern for the hackathon elements of a telecom services to provide stopping we also perform the remix valuing the width of the leads, at the same time it's been one again.
Barbara Clerbaux: And maybe to show you know we try to have legacy papers have to really have.
Barbara Clerbaux: to extract as much as possible information from the data.
Barbara Clerbaux: We also confirm interpretation of these limits in a CD CD God, so if you have a modality, the coupling.
Barbara Clerbaux: Too into the weeds you prefer at cooking you can know he's the meeting that flood, and also in the previous episode before.
Barbara Clerbaux: I see me from the movie theater.
Barbara Clerbaux: Maybe it's a mass.
Barbara Clerbaux: Of.
Barbara Clerbaux: matter analysis.
Barbara Clerbaux: Within a certain supporting the second talking between the media during class and maybe and the back.
Barbara Clerbaux: So you see, you see the title of the legacy paper from from this beta attendee to extract as much as possible information.
Barbara Clerbaux: To exclude as much as possible, please, please.
Barbara Clerbaux: accept our models.
Barbara Clerbaux: In the same spirit search for feminine but also in the Center of nomination process.
Barbara Clerbaux: For these events has been divided into our values being math and personal tester you can do.
Barbara Clerbaux: and stand for something experiment using these beans and then you can put lower limits on this together, so the less number of theater.
Barbara Clerbaux: In the framework of contact interaction or identifying work with excited I mentioned mother So here we do not expect settlements in the spectrum, but he has expect the modification of the shape of a mass and then clicking.
Barbara Clerbaux: On this, what is new hearing the message that we also lose information after Christmas data, and so we divided in category is pessimistic TV vivo and pacifica greater than zero and designers to separate the contribution.
Barbara Clerbaux: You see, the angle to the vendor of the leptin compared to the correct direction in the console.
Barbara Clerbaux: And another thing that we did in this paper is to check the lip balm flavor universality and what do we do we do a ratio of the environment, mass.
Barbara Clerbaux: spec home from the new new to the E and, in fact, is a wi fi issue that we do so, we compare the new to erase your from data to the one in Monte Carlo.
Barbara Clerbaux: And this is key to pull to pull over the Neptune flavor university Dr nation at the TV screen, this is really done for the first time now at etc.
Barbara Clerbaux: And you can see the results here when the two leptons are in the Batman and when you have one left on in the gaps in the fourth part of the detector.
Barbara Clerbaux: And you see that we have with agreement in the ratio.
Barbara Clerbaux: is maybe a bit of a.
Barbara Clerbaux: shoo shoo point a bit of attention is fine.
Barbara Clerbaux: So I will.
Barbara Clerbaux: Well, he said just to work on the CD if you're a student fan, please have a look at the.
Barbara Clerbaux: At the paper is just tell you that this is a new update that preserves of the quite standard search know of electronic and some production with the dialect on finance date.
Barbara Clerbaux: So here we interpret the results men in simplified model spectrum, where you support that the particle that you are looking.
Barbara Clerbaux: susie back to give me the heaviest one and give, for example, in case of have slept on the key into leaped on an exciting, though, is 100% attention protection.
Barbara Clerbaux: And then you can have such kind of excrement blood, and so this is for slept on which you can have for the squad for bottom for the Reno the shadier node and let me know and you see know that we go for the for this for the squawk to.
Barbara Clerbaux: For the for the bottom quark squawk and for the for the light squad up to 1.8 TV for the Lino is is nearly 1.9 these are going high know in the in the experiment was.
Barbara Clerbaux: The same for susie for the STOP what their production again in the dinette on finances, so this is also an update, with the full time to data set and you see that the exclusion, depending on the channel is feeling very close to one TV.
Barbara Clerbaux: So I have to be a bit fast, because I can relate, but for those who are interested in search for lonely particle and we have new hazards.
Barbara Clerbaux: Looking for the King jet into displays ethics, so you can see here all the day comes, can have topology we are targeting so it's quite a lot of possible to quality, so we do inclusive search, but they are indicated in many modern.
Barbara Clerbaux: We use the data taken 17 and 18 but you combine with the previous results and the department.
Barbara Clerbaux: really important we improve the nuclear interaction veto map, as you can see here and not have to be checked the backhand and you also use machine learning techniques to improve so that'll be.
Barbara Clerbaux: An improvement compared to previous analysis, this is the train button rejection so it's important and so depending on on the.
Barbara Clerbaux: On the model that you prefer you can be a value suit and he had just put and just to example you have much more in the paper and also there is a dedicated people here.
Barbara Clerbaux: Which is clearly optimized to.
Barbara Clerbaux: to lower six evaluating between 100 micrometres.
Barbara Clerbaux: This summer.
Barbara Clerbaux: People that focus for low low displacement.
Barbara Clerbaux: OK, so the last one I wanted to do this to present to adapt for done in video production, where you see for the first time the amenities of http two foot on enter that for them.
Barbara Clerbaux: In PDF events, so we have to forward it to get the video production we have large make an isolated type up for you can see here event assumption of the transverse mass, which is the funniest most of the photon that you see and have the conversation and then.
Barbara Clerbaux: You see how clean.
Barbara Clerbaux: Is the selection of very few but hundreds of course you will also have to signal, depending on what.
Barbara Clerbaux: mentioned fashion, your food, and you can see the needs that thing for this analysis and actually you can also combine it with the age analysis and if you didn't cms and so you have the upper limit on the vm this new analysis conducted hmm can combine the two and.
Barbara Clerbaux: The more sensitive need for this age to Ghana.
Barbara Clerbaux: Okay, so this.
Barbara Clerbaux: finalize the business of them to live, I want to show you the activity during lunch of dawn to if you're interested in and the slide.
Barbara Clerbaux: Now, expensive, we have a lot of activities, of course.
Barbara Clerbaux: Maybe two words of what we are going to do 41373 is of course the doubling the statistics to so we have about two times more data.
Barbara Clerbaux: But we will have to be more innovative, to take more of the data, because just affected to be nice if this is not so much.
Barbara Clerbaux: So that the goal is to be do this the medical certainty and for the position to us again machine learning as much as possible, so when when it's relevant, of course.
Barbara Clerbaux: I will try, also to understand and to cover the gaps of the analysis or the more exotic you're the kenai can be back to them, and so on, so we try to have new idea, in particular, we can design to also for the hunting is what you're working on, for the moment.
Barbara Clerbaux: But also cms will change and will change, and so we exploit inventing new detector.
Barbara Clerbaux: For example, I have put here for four bullets, we will have a desk segmentation now in the age can we have a first phase one pixel detector of the Level one electronics or the attacker.
Barbara Clerbaux: We have no also Firstly, you have genuine detector in the forest region, and we also planning to move to it, then for joining us today pitch it to go missing some few inches.
Barbara Clerbaux: So, all this will be used, of course, to improve the detector 400.
Barbara Clerbaux: Okay, so first to the conclusion I have shown you that we have we have very nice wizards of the village see the year 2020 and 2021, despite the fact that it was very difficult year due to the damage.
Barbara Clerbaux: So I just highlight the standard model measurement with the polis WW moment the first observation of vv the very, very short small construction Murat in.
Barbara Clerbaux: The plus two jet's etc, in the heat sector, the main hurdles, of course, is the measurement of evidence of each new copying and for dynamic search, we have no time limit, thanks to the full time to data analysis and you also probing more and more difficult final state.
Barbara Clerbaux: The Vb production is no widely considered anything that is important, the machine learning algorithm i've also been implemented many analysis for particular construction signal extraction and so on.
Barbara Clerbaux: We have new reserves on the full one two analogies to come, of course.
Barbara Clerbaux: And to come soon actually because mobile is next week so it's a pity that this seminar was not one or two weeks later, because are very nice reserves that will be present next week, so if you're interested, please.
Barbara Clerbaux: Have a look at the latest versions of cms in the public page in the coming weeks, four weeks.
Barbara Clerbaux: And of course we have the country and.
Barbara Clerbaux: And then the St Louis that was coming to a medium and.
Barbara Clerbaux: Thank you for your attention and sorry for being a bit a bit late.
Ivana Hristova: Thank you very much.
