First data from the CUPID-Mo neutrinoless double beta decay experiment
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.
