Results from the CUORE experiment
Abstract
The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for neutrinoless double beta decay (0νββ) 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 0νββ 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 0νββ half-life of T^{0ν}_{1/2}>1.3×10^{25} yr (90% C.L.).
