Update on the Status of the CUPID-Mo Demonstrator

CUORE is the first ton-scale cryogenic bolometer experiment searching for neutrinoless double-beta decay. The successor to CUORE, called CUPID, is designed to improve the half-life sensitivity of CUORE by almost two orders of magnitude and fully probe the so-called “inverted hierarchy” region of the effective majorana neutrino mass. The technology for CUPID is currently being employed in the CUPID-Mo demonstrator, which is searching for the 0$\nu\beta\beta$ decay of $^{100}$Mo. CUPID-Mo consists of 20 enriched $\sim$0.2 kg Li$_{2}{}^{100}$MoO$_4$ scintillating crystals, complemented by 20 light-detecting Ge bolometers. By comparing the heat vs light signals, CUPID-Mo is able to distinguish $\alpha$ events from $\beta/\gamma$ events for a powerful background discriminant. CUPID-Mo began data taking in Spring 2019. In this talk, we will present early results from the first data collected with CUPID-Mo, an updated prediction for its expected sensitivity, and an outlook on the prospects of CUPID.
