CUORE/CUORICINO: Double Beta Decay with low temperature detectors

CUORICINO is an array of 62 TeO2 bolometers designed to search for the ββ(0ν) of 130Te. With a total mass of 40.7 kg of TeO2, corresponding to about 11 kg of 130Te, CUORICINO has collected up to now a total statistics of 8.38 kg(130Te) y. No evidence for the 2530 keV peak that should be produced by ββ(0ν) events is found. The upper limit on the half life 2.4x1024 years at 90% C.L. is converted into a lower bound on the neutrino effective Majorana mass of 0.18-0.9 eV. CUORE, a one ton scale experiment based on the CUORICINO technology and intended to push Majorana mass sensitivity for 130Te ββ(0ν) toward the inverted hierarchy region, is here discussed
