Description

CUORE is a 1-Ton experiment made of about 1000 TeO2 bolometers. It will probe the neutrinoless double beta decay (0nuDBD) of 130Te, a tool to test the neutrino nature and mass. The experimental technique has been proved in CUORICINO, a 40 Kg experiment that recently set a new limit on the 0nuDBD half-life. The excellent energy resolution and the low background of these detectors will make CUORE a leading experiment in this field, improving the sensitivity to the half-life of 0nuDBD by more than an order of magnitude. Bolometric detectors, however, are also sensitive to nuclear recoils and can be used to search for Dark Matter interactions. In principle CUORE, thanks to its mass, could look for an annual modulation of the counting rate at low energies. We are developing a pulse shape identification algorithm, applicable as an on-line trigger, that allows to lower the energy threshold down to the few keV region. We present the preliminary results obtained on an array made of four CUORE-like crystals (44 kg*days), and the prospects for a Dark Matter search in CUORE.
