Institute for Nuclear and Particle Astrophysics (INPA) at LBNL

The INPA Seminar weekly talks are on Fridays, starting at 12:00 pm, unless informed otherwise. The seminar talk starts with a brief presentation of the weekly scientific news. Typically, the talks conclude by 1:00 pm. The seminars are held in the Sessler Conference Room,  located in Bldg. 50A- 5132.

The committee members are:

The seminar schedule for the Institute for Nuclear and Particle Astrophysics (INPA) is tentative and becomes final a few days before the Friday talk.

Please send all suggestions for future INPA talks and speakers to the INPA Committee.

TITLE: Investigation of the Majorana nature of neutrinos at a few meV level of the neutrino mass scale: from CUPID to BINGO

ABSTRACT: The search for neutrinoless double beta decay (0ν2β) is one of the biggest experimental challenges of contemporary physics. Its discovery would be ground- breaking since it would prove the Majorana nature of neutrinos, give an insight into neutrino mass scale, and provide clues to explain the matter/antimatter asymmetry of our Universe. Cryogenic calorimeters are promising devices for this purpose as CUORE, the ton-scale experiment constructed with such detectors, is demonstrating by setting the most stringent limit on Te-130 0ν2β half-life and being one of the most sensitive current generation experiments. However, its sensitivity is limited by the background. Its successor, the next-generation experiment CUPID, will reach a higher sensitivity by reducing the number of expected background events in the region of interest. It will study as the candidate isotope Mo-100 embedded inside Li2MoO4 scintillating crystals, which allows mitigating the Ɣ background naturally while also introducing a dual heat/light readout using an auxiliary Ge bolometer to get rid of the α background. Thanks to that, CUPID will improve the CUORE sensitivity by two orders of magnitude. At that point, if 0ν2β still eludes us, the background reduction must be pushed even further. BINGO is a project aiming to prepare the next-next generation of bolometric experiments by proposing innovations and methods for that purpose. For example, it will reduce the remaining Ɣ and β background contributions thanks to respectively a cryogenic active veto and a revolutionary detector assembly. BINGO will demonstrate that, once implemented in a ton-scale isotope experiment, its improvements will allow the latter to reach a sensitivity to neutrino mass scale below 10 meV. In that talk, the current status of the CUPID experiment will be discussed and the R&D work done in the framework of the BINGO project will be presented.
