Abstract

The Cryogenic Underground Observatory for Rare Events (CUORE) is the first cryogenic experiment searching for $$$$0\nu \beta \beta $$$$ $0\nu \beta \beta$ decay that has been able to reach the one-tonne mass scale. The detector, located at the Laboratori Nazionali del Gran Sasso (LNGS) in Italy, consists of an array of 988 $$$${\mathrm{TeO}}_{2}$$$$ ${\mathrm{TeO}}_2$ crystals arranged in a compact cylindrical structure of 19 towers. CUORE began its first physics data run in 2017 at a base temperature of about 10 mK and in April 2021 released its $$$$3{\mathrm{rd}}$$$$ $3\mathrm{rd}$ result of the search for $$$$0\nu \beta \beta $$$$ $0\nu \beta \beta$ , corresponding to a tonne-year of $$$$\mathrm{TeO}_{2}$$$$ ${\mathrm{TeO}}_2$ exposure. This is the largest amount of data ever acquired with a solid state detector and the most sensitive measurement of $$$$0\nu \beta \beta $$$$ $0\nu \beta \beta$ decay in $$$${}^{130}\mathrm{Te}$$$$ ${}^{130}\mathrm{Te}$ ever conducted . We present the current status of CUORE search for $$$$0\nu \beta \beta $$$$ $0\nu \beta \beta$ with the updated statistics of one tonne-yr. We finally give an update of the CUORE background model and the measurement of the $$$${}^{130}\mathrm{Te}$$$$ ${}^{130}\mathrm{Te}$ $$$$2\nu \beta \beta $$$$ $2\nu \beta \beta$ decay half-life and decay to excited states of $$$${}^{130}\mathrm{Xe}$$$$ ${}^{130}\mathrm{Xe}$ , studies performed using an exposure of 300.7 kg yr.
