Description
The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for 0νββ decay that has successfully reached the one-tonne mass scale. It is the most sensitive probe searching for lepton number violation and the Majorana nature and mass scale of neutrinos in the isotope $^{130}$Te. The detector, located at the LNGS in Italy, consists of an array of 988 TeO$_2$ crystals (750 kg) arranged in a compact cylindrical structure of 19 towers. CUORE has been collecting data continuously at ~10 mK since 2017, achieving a ~90% uptime and amassing close to 3 tonne-years of TeO$_2$ exposure. In Oct 2025 the collaboration published the most recent result of the search for 0νββ, corresponding to two tonne-year TeO$_2$ exposure. This is the largest amount of data ever acquired and analyzed with a solid state cryogenic detector, which allowed for further improvement in the CUORE sensitivity. In this talk, we will review the current status of the CUORE search for 0νββ and the CUORE science program. The large statistics also allows for one of the most detailed background reconstructions in the field and enabled a precision measurement of the $^{130}$Te 2νββ decay half-life.
