Review of the properties of the neutrinoless double beta decay

Abstract

In this work we investigate general properties of the nuclear matrix elements (NMEs) related to the neutrinoless double β − decays (0νβ−β − decays) of several nuclei of interest for double-beta-decay experiments. A summary of the values of the NMEs calculated along the years by the Jyv¨askyl¨a–La Plata collaboration is given. These NMEs are compared with those of the other available calculations and general conclusions are drawn based on these comparison
