The Cryogenic Underground Observatory for Rare Events (CUORE) is the first cryogenic experiment searching for neutrinoless double-beta (0 ) decay that has been able to reach the one-ton scale. The detector, located at the Laboratori Nazionali del Gran Sasso in Italy, consists of an array of 988 TeO 2 crystals arranged in a compact cylindrical structure of 19 towers. Following the completion of the detector construction in August 2016, CUORE began its first physics data run in 2017 at a base

In 2019, CUORE released its 2 nd result of the search for 0 with a TeO 2 exposure of 372.5 kg·yr and a median exclusion sensitivity to a 130 Te 0 decay half-life of 1.7 · 10 25 yr. We find no evidence for 0 decay and set a 90% C.I. (credibility interval) Bayesian lower limit of 3.2 · 10 25 yr on the 130 Te 0 decay half-life. In this work, we present the current status of CUORE's search for 0 , as well as review the detector performance. Finally, we give an update of the CUORE background model and the measurement of the 130 Te two neutrino double-beta (2 ) decay half-life. ICHEP2020
