Experiments Background, Models and Simulations

Presentation

Next generation neutrinoless double beta decay experiments aim to search for lepton number violation and the origin of neutrino mass through ton-scale experiments with ever more demanding background targets. In order to cover neutrino masses in the inverted hierarchy region, half-life sensitivities equal to or greater than 10$^{27}$ years are required. The CUPID experiment is one of the...

Experiments Background, Models and Simulations

Presentation

The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for 0νββ decay that has successfully reached the one-tonne mass scale. It is the most sensitive probe searching for lepton number violation and the Majorana nature and mass scale of neutrinos in the isotope $^{130}$Te. The detector, located at the LNGS in Italy, consists of an array of...

26. Every Alpha, Every Decay Chain, All at Once

Presentation

The SNO+ collaboration has developed a likelihood-based method to identify and tag previously inaccessible backgrounds arising from the $^{238}\mathrm{U}$ and $^{232}\mathrm{Th}$ decay chains. The method combines the time and spatial separations between candidate events with energy PDFs to evaluate correlations within radioactive decay sequences. In contrast to the sub-millisecond half-lives...

20. Neutron detection and potential for rare decay searches with low background GAGG detectors

Experiments Background, Models and Simulations

Presentation

A precise measurement of neutrons is crucial for underground experiments searching for rare events. The neutron component is often poorly known due to the lack of a scalable detector technology for the measurement of low-flux neutron spectra in a short time. Thanks to their high gadolinium content, we have demonstrated the possibility of using scintillating cerium-doped...
