Different approaches to CUORE background analysis

Neutrino oscillation experiments have unequivocally demonstrated that neutrinos have mass and that neutrino mass eigenstates mix. One possible way to determine the scale of the neutrino mass and its nature is to investigate the neutrinoless double-beta decay(0νdbd). The CUORE experiment is designed with a sensitivity capable of probing all but a small portion of the Majorana electron neutrino effective mass range. CUORE is an array of 988 TeO2 bolometers. The signal of neutrinoless double-beta decay for 130Te would be a sharp peak at 2530 keV. The rarity of the process under consideration makes its identification very difficult. The main task in 0νdbd searches is to understand and to diminish the background as much as possible. In order to reach this goal, different techniques are employed: Monte Carlo simulations, alpha-spectroscopy and pulse shape discrimination. © Società Italiana di Fisica.
