Effective Majorana mass and neutrinoless double beta decay

The CUORE (Cryogenic Underground Observatory for Rare Events) experiment will search for neutrinoless double beta decay of <sup>130</sup>Te, a rare nuclear process that, if observed, would demonstrate the Majorana nature of the neutrino and enable measurements of the effective Majorana mass. The CUORE setup consists of an array of 988 tellurium dioxide crystals, operated as bolometers, with a total mass of about 200 kg of <sup>130</sup>Te. The experiment is under construction at the Gran Sasso National Laboratory in Italy. As a first step towards CUORE, the first tower (CUORE-0) has been assembled and will soon be in operation.

The main purpose of the Cryogenic Underground Observatory for Rare Events (CUORE) experiment is the search for the Neutrinoless Double Beta Decay (0νDBD) of 130 Te reaching a sensitivity on Majorana mass better than 50 meV. Cuoricino represents not only the first stage of CUORE, but also the most massive 0νDBD experiment presently running. Present results and future planning of these experiments will be described in the paper.

The consequences of a texture zero at the ee entry of neutrino mass matrix in the flavor basis, which also implies a vanishing effective Majorana mass for neutrinoless double beta decay, have been studied for Majorana neutrinos. The neutrino parameter space under this condition has been constrained in the light of all available neutrino data including the CHOOZ bound on [Formula: see text].

In this brief review we discuss the generation of Majorana neutrino masses through the seesaw mechanism, the theory of neutrinoless double-beta decay, the implications of neutrino oscillation data for the effective Majorana mass, taking into account the recent Daya Bay measurement of ϑ13, and the interpretation of the results of neutrinoless double-beta decay experiments.
