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.

Title: Towards the meV level of neutrino mass scale: from CUPID to BINGO
Abstract: Neutrinoless double-beta decay (0v2b) is a key process in the search for Majorana neutrinos. Its observation would confirm the violation of lepton number conservation, demonstrating that neutrinos are their own antiparticles, and provide crucial insight into the absolute neutrino mass scale and hierarchy. The CUPID (CUORE Upgrade with Particle ID) experiment aims to achieve the sensitivity required to probe the inverted hierarchy region of the effective Majorana mass. It will employ an array of scintillating bolometers composed of Li2MoO4 (LMO) crystals enriched in Mo-100, coupled with Ge bolometric light detectors. This dual heat-light readout enables an efficient rejection of the alpha background, which currently limits the sensitivity of its predecessor, CUORE. CUPID aims to reach an unprecedented background index of 1e-4 counts/kg/keV/year (ckky) in the region of interest (ROI) and to establish the technology required for a future ton-scale bolometric 0v2b experiment. Beyond CUPID, further sensitivity improvements are necessary to probe the normal hierarchy region. The BINGO (Bi-Isotope 0v2b Next Generation Observatory) project introduces novel strategies to reduce background levels to 1e-5 ckky for the simultaneous study of Mo-100 and Te-130 isotopes. It proposes three main technological improvements that should help to drastically reduce background in ROI, including innovative detector assembly, cryogenic active veto, and Neganov-Trofimov-Luke light detectors. This talk will provide a general review of the current status of 0v2b decay bolometric experiments, along with the most recent results of R&D work conducted within the BINGO project framework.
