Measurement of the two-neutrino double-beta decay half-life of ^{130}Te with the CUORE-0 experiment
Abstract
We report on the measurement of the two-neutrino double-beta decay half-life of ^{130}Te with the CUORE-0 detector. From an exposure of 33.4 kg year of TeO_2, the half-life is determined to be T_{1/2}^{2ν } = [8.2 ± 0.2 (stat.) ± 0.6 (syst.)] × 10^{20} 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 contributing to the ^{130}Te neutrinoless double-beta decay region of interest.
