Abstract

The Cryogenic Underground Observatory for Rare Events (CUORE) is the frst cryogenic experiment searching for 0vββ decay that has been able to reach the onetonne mass scale. The detector, located at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy, consists of an array of 988 TeO₂ crystals arranged in a compact cylindrical structure of 19 towers. CUORE began its frst physics data run in 2017 at a base temperature of about 10 mK and in April 2021 released its 3rd result of the search for 0vββ, corresponding to a tonne-year of TeO₂ exposure. This is the largest amount of data ever acquired with a solid state detector and the most sensitive measurement of 0vββ decay in ¹³⁰Te ever conducted . We present the current status of CUORE search for 0vββ with the updated statistics of one tonne-yr. We fnally give an update of the CUORE background model and the measurement of the ¹³⁰Te 2vββ decay half-life and decay to excited states of ¹³⁰Xe, studies performed using an exposure of 300.7 kg yr.
