Abstract

The CUPID-Mo experiment is searching for neutrinoless double beta decay in $^{100}$ Mo, evaluating the technology of cryogenic scintillating Li $_{2}^{100}$ MoO $_4$ detectors for CUPID (CUORE Upgrade with Particle ID). CUPID-Mo detectors feature background suppression using a dual-readout scheme with Li $_{2}$ MoO $_4$ crystals complemented by Ge bolometers for light detection. The detection of both heat and scintillation light signals allows the efficient discrimination of $\alpha$ from $\gamma$ & $\beta$ events. In this proceedings, we discuss results from the first 2 months of data taking in spring 2019. In addition to an excellent bolometric performance of 6.7 $\,$ keV (FWHM) at 2615 $\,$ keV and an $\alpha$ separation of better than 99.9\% for all detectors, we report on bulk radiopurity for Th and U. Finally, we interpret the accumulated physics data in terms of a limit of $T_{1/2}^{0\nu}\,> 3\times10^{23}\,$ yr for $^{100}$ Mo and discuss the sensitivity of CUPID-Mo until the expected end of physics data taking in early 2020.
