We report on the measurement of the two-neutrino double-beta decay half-life of 130Te with the CUORE-0 detector.

This result is obtained after a detailed reconstruction of the sources responsible for the CUORE-0 counting rate, with a specific study of those con- tributing to the 130Te neutrinoless double-beta decay region of interest.

Abstract
We report on the measurement of the two-neutrino double-beta decay half-life of 130Te with the CUORE-0 detector. From an exposure of 33.4 kg year of TeO2, the half-life is determined to be T2ν = [8.2 ± 0.2 1/2 (stat.) ± 0.6 (syst.)] × 1020 year. This result is obtained after a detailed reconstruction of the sources responsible for the CUORE-0 counting rate, with a specific study of those con- tributing to the 130Te neutrinoless double-beta decay region of interest.| File | Dimensione | Formato | |
