DESCRIPTION:Speakers: Lorenzo Pagnanini ()\nA convincing observation of ne
 utrino-less double beta decay (0𝜈DBD) relies on the possibility of oper
 ating high-energy resolution detectors in background-free conditions.\nSci
 ntillating cryogenic calorimeters are one of the most promising tools to f
 ulfill the requirements for a next-generation experiment. Several steps ha
 ve been taken to demonstrate the maturity of this technique\, starting for
 m the successful experience of CUPID-0.\nThe CUPID-0 experiment demonstrat
 ed the complete rejection of the dominant alpha background measuring the l
 owest counting rate in the region of interest for this technique. Furtherm
 ore\, the most stringent limit on the Se-82 0𝜈DBD was established runni
 ng 26 ZnSe crystals during two years of continuous detector operation.\nIn
  this contribution we present the final results of CUPID-0 Phase I includi
 ng a detailed model of the background\, the measurement of the 2𝜈DBD ha
 lf-life and the evidence that this nuclear transition is single state domi
 nated. The first results obtained after the upgrade of the detector in 201
 9 are presented as well.\n\nhttps://indico.tlabs.ac.za/event/85/contributi
