Universality of the Majorana Double Charge Exchange

Caterina Garofalo, Horst Lenske, Francesco Cappuzzello, Manuela Cavallaro

Abstract

The Majorana Double Charge Exchange nuclear reaction mechanism represents a powerful and novel scenario to probe the dynamics of the neutrinoless double beta decay. Recent studies presented in this manuscript have highlighted a key feature of this mechanism, namely its independence with respect to the nuclei involved in the reaction.
