Status of cupid-mo

CUPID-Mo is a bolometric experimental demonstrator searching for neutrinoless double beta (0ν2β) decay of 100Mo. The observation of this process, which is not allowed by the Standard Model, would determine the Majorana nature of neutrino and its mass scale. The CUPID-Mo detector array consists of 20 scintillating bolometers made of Li2100MoO4 crystals (2.34 kg of 100Mo), assembled in a compact structure of 5 suspended towers. Data taking will start soon in the EDELWEISS cryostat at the Underground Laboratory of Modane (LSM, France). The main goal of the CUPID-Mo experiment is to demonstrate “zero-background” conditions in the region of the expected 0ν2β decay signal of 100Mo over six months of measurement. The reproducibility of Li2100MoO4 scintillating bolometers with high performance should be confirmed, demonstrating the applicability of the CUPID-Mo technology for the future ton-scale 0ν2β decay bolometric experiment CUPID.
