The Cryogenic Underground Observatory for Rare Events (CUORE) is a ton-scale neutrinoless double beta decay experiment based on cryogenic bolometers that is in the final stage of construction at the Gran Sasso National Laboratory (LNGS). CUORE is aimed at observing the neutrinoless double beta decay of 130Te and measuring the corresponding Majorana neutrino mass with a sensitivity close to the so-called inverted mass hierarchy region. CUORE-0 is the demonstrator of CUORE: a single CUORE-like tower, made of 52 TeO2 bolometers for a total mass of 39 kg. CUORE-0 started taking data in spring 2013 at LNGS and reached a total exposure of 9.8 kg y of 130Te. CUORE-0 significantly reduces the background and energy resolution of the previous experiment CUORICINO and sets the most stringent limit to date on neutrinoless double beta decay in 130Te. We will discuss in the following the physics results from CUORE-0 data and the status of the construction of CUORE.

Abstract

The Cryogenic Underground Observatory for Rare Events (CUORE) is a ton-scale neutrinoless double beta decay experiment based on cryogenic bolometers that is in the final stage of construction at the Gran Sasso National Laboratory (LNGS). CUORE is aimed at observing the neutrinoless double beta decay of 130Te and measuring the corresponding Majorana neutrino mass with a sensitivity close to the so-called inverted mass hierarchy region. CUORE-0 is the demonstrator of CUORE: a single CUORE-like tower, made of 52 TeO2 bolometers for a total mass of 39 kg. CUORE-0 started taking data in spring 2013 at LNGS and reached a total exposure of 9.8 kg y of 130Te. CUORE-0 significantly reduces the background and energy resolution of the previous experiment CUORICINO and sets the most stringent limit to date on neutrinoless double beta decay in 130Te. We will discuss in the following the physics results from CUORE-0 data and the status of the construction of CUORE.
