Description

The CUPID-Mo experiment, currently taking data at the Laboratoire Souterrain de Modane (France), is a demonstrator for a next-generation upgrade of the first ton-scale cryogenic $0\nu\beta\beta$-search, CUORE. The experiment is probing $0\nu\beta\beta$ of $^{100}$Mo with an array of 20 enriched 0.2 kg Li$_2$MoO$_4$ crystals and Ge light detectors allowing to distinguish $\alpha$ from $\beta/\gamma$ events by the detection of both heat and scintillation light signals. For the present analysis, we will employ the excellent bolometric performance of down to 5-6 keV energy resolution (FWHM) at 2615 keV, full $\alpha$-to-$\beta/\gamma$ separation and excellent radio-purity levels to perform a competitive search for $0\nu\beta\beta$ of $^{100}$Mo. With more than 2 kg$\cdot$yr of exposure an exclusion sensitivity comparable to the leading limit from NEMO-3 is expected.
