Abstract

The Cryogenic Underground Observatory for Rare Events (CUORE) is the first cryogenic experiment searching for neutrinoless double-beta (0νββ0\nu\beta\beta) 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 TeO2_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 temperature of about 10 mK. Following multiple optimization campaigns in 2018, CUORE is currently in stable operating mode. In 2019, CUORE released its 2\textsuperscript{nd} result of the search for 0νββ0\nu\beta\beta with a TeO2_2 exposure of 372.5 kg\cdotyr and a median exclusion sensitivity to a 130^{130}Te 0νββ0\nu\beta\beta decay half-life of 1.710251.7\cdot 10^{25} yr. We find no evidence for 0νββ0\nu\beta\beta decay and set a 90\% C.I. (credibility interval) Bayesian lower limit of 3.210253.2\cdot 10^{25} yr on the 130^{130}Te 0νββ0\nu\beta\beta decay half-life. In this work, we present the current status of CUORE's search for 0νββ0\nu\beta\beta, as well as review the detector performance. Finally, we give an update of the CUORE background model and the measurement of the 130^{130}Te two neutrino double-beta (2νββ2\nu\beta\beta) decay half-life.
