Effective Majorana mass and neutrinoless double beta decay


Benato, Giovanni (2015). Effective Majorana mass and neutrinoless double beta decay. European Physical Journal C - Particles and Fields, 75:563.

Abstract

The probability distribution for the effective Majorana mass as a function of the lightest neutrino mass in the standard three neutrino scheme is computed via a random sampling from the distributions of the involved mixing angles and squared mass differences. A flat distribution in the [0,2π] range for the Majorana phases is assumed, and the dependence of small values of the effective mass on the Majorana phases is highlighted. The study is then extended with the addition of the cosmological bound on the sum of the neutrino masses. Finally, the prospects for 0νββ decay search with76 Ge,130 Te and136 Xe are discussed, as well as those for the measurement of the electron neutrino mass.
