New Limit for Neutrinoless Double-Beta Decay of Mo-100 from the CUPID-Mo Experiment
Original language description
The CUPID-Mo experiment at the Laboratoire Souterrain de Modane (France) is a demonstrator for CUPID, the next-generation ton-scale bolometric 0 nu beta beta experiment. It consists of a 4.2 kg array of 20 enriched (Li2MoO4)-Mo-100 scintillating bolometers to search for the lepton-number-violating process of 0 nu beta beta decay in Mo-100. With more than one year of operation (Mo-100 exposure of 1.17 kg x yr for physics data), no event in the region of interest and, hence, no evidence for 0 nu beta beta is observed. We report a new limit on the half-life of 0 nu beta beta decay in Mo-100 of T-1/2 > 1.5 x 10(24) yr at 90% C.I. The limit corresponds to an effective Majorana neutrino mass < m(beta beta)> < (0.31-0.54) eV, dependent on the nuclear matrix element in the light Majorana neutrino exchange interpretation.
