Description
The CUPID-Mo experiment is devoted to the search of neutrinoless double beta decay, 2β0ν. This small-scale array of scintillating bolometers has set in 2020 the best limit to the half-live of 2β0ν in 100Mo, with 2.17 kg x y of exposure. CUPID-Mo has demonstrated the maturity of the scintillating bolometric technique for CUPID (Cuore Upgrade with Particle Identification), the next generation 2β0ν ton-scale cryogenic experiment.
CUPID-Mo consists of 20 enriched Li2100MoO4 scintillating crystals, at the Laboratoire Souterrain de Modane (France). The simultaneous measurement of heat and light allows rejecting the α background.
In this talk we will present the data analysis corresponding to a 380 day period acquired between March 2019 and April 2020. This analysis lead to the new limit on 2β0ν in 100Mo of T1/2 > 1.5 x 10^24 yr at 90% CI, corresponding to an effective Majorana mass < (0.31 – 0.54) eV.
