Cuoricino is a taking data bolometric experiment searching for neutrinoless double beta decay (0vDBD) of 130Te. The detector consists of an array of large cubic Te02 crystal bolometers.

The counting rate in the region of 0vDBD is 0.18±0.02 c/keV/kg/y. The limit for the 0vDBD half lifetime is 2.0 ± 1024 years at the 90% of C.L. This results correspond to a limit for the effective neutrino mass between 0.2 and 1.0 eV, depending on the nuclear matrix elements used. A large international collaboration is working on CUORE project, a future experiment with a mass of 741 kg of TeO2 crystal bolometers. The experiment aims to probe the neutrino absolute mass down to 50 meV and to understand if the inverted hierarchy holds in the neutrino mass pattern.

Abstract

Cuoricino is a taking data bolometric experiment searching for neutrinoless double beta decay (0vDBD) of 130Te. The detector consists of an array of large cubic Te02 crystal bolometers. Cuoricino works at about 10 mK in the Gran Sasso Underground Laboratory. Good energy resolutions were obtained (2.1 keV at 911 keV and 3.9 keV at 2615 keV at best). The counting rate in the region of 0vDBD is 0.18±0.02 c/keV/kg/y. The limit for the 0vDBD half lifetime is 2.0 ± 1024 years at the 90% of C.L. This results correspond to a limit for the effective neutrino mass between 0.2 and 1.0 eV, depending on the nuclear matrix elements used. A large international collaboration is working on CUORE project, a future experiment with a mass of 741 kg of TeO2 crystal bolometers. The experiment aims to probe the neutrino absolute mass down to 50 meV and to understand if the inverted hierarchy holds in the neutrino mass pattern.
