Abstract
The nature of neutrino mass is one of the friontier problems of fundamental physics. Neutrinoless Double Beta Decay (0νDBD) is a powerful tool to investigate the mass hierarchy and possible extensions of the Standard Model. CUORICINO is a bolometric experiment that has set a lower limit on the 0νDBD of 130Te of 3.1 × 1024 y (90% C.L.) with a total statistic of 15.53 kg. CUORE is a 1-Ton next generation experiment, made of ∼ 1000 Te bolometers, aiming at reaching a background of 0.01 (possibly 0.001) counts/keV/kg/y and therefore a mass sensitivity of few tens of meV. The last CUORICINO results and CUORE prospects are reported. © 2009 Elsevier B.V.
