Abstract

CUORE is a 741 kg array of 988 TeO₂ bolometeric crystals designed to\nsearch for the neutrinoless double beta decay of ¹³⁰Te and other rare\nprocesses. CUORE has been taking data since summer 2017, and as of summer 2018\ncollected a total of 86.3 kg\⋅yr of TeO₂ exposure. Based on this\nexposure, we were able to set a limit on the 0\ν\β\β half-life of\n¹³⁰Te of T^0\ν_1/2>1.5\×10²⁵ yr at 90% C.L. At this\nconference, we showed the decomposition of the CUORE background and were able\nto extract a ¹³⁰Te 2\ν\β\β half-life of\nT_1/2^2\ν=[7.9\±0.1 \(stat.)\±0.2\n\(syst.)]\×10²⁰ yr. This is the most precise measurement of\nthis half-life and is consistent with previous measurements.\n
