The CUORE Collaboration

Monday Session, Poster Wall #38 (Auditorium Gallery Right)

The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for neutrinoless double beta decay ($0\nu\beta\beta$) that has been able to reach the one-ton scale. The detector consists of an array of 988 TeO${2}$ crystals arranged in a compact cylindrical structure of 19 towers. The construction of the experiment was completed in August 2016 with the installation of all towers in the cryostat. Following a cooldown, diagnostic, and optimization campaign, routine data-taking began in spring 2017. In this poster, we present the $0\nu\beta\beta$ results of CUORE from examining a total TeO${2}$ exposure of 86.3 kg$\cdot$yr, characterized by an average energy resolution of 7.7 keV FWHM and a background in the region of interest of 0.014 counts/(keV$\cdot$kg$\cdot$yr). In this physics run, CUORE placed a lower limit on the $^{130}$Te $0\nu\beta\beta$ half-life of $T^{0\nu}_{1/2}>1.3\times10^{25}$ yr (90% C.L.).
