Search for neutrinoless double beta decay with the CUORE detector

Abstract

CUORE (Cryogenic Underground Observatory for Rare Events) is a 1-ton experiment to search for Neutrinoless Double Beta Decay of 130Te using 988 TeO2 bolometers. It aims at reaching the sensitivity on the effective neutrino mass of the order of few tens of meV. CUORICINO, a single CUORE tower running since 2003 in the Gran Sasso Underground Laboratory (Italy), plays an important role as a standing alone experiment for developing the future CUORE setup. The latest limit obtained on the Majorana mass is presented. The effort in improving the detector sensitivity and background reduction is also reported.
