Abstract

The Majorana Double Charge Exchange (MDCE) provides a suitable environment for studying the dynamics of the neutrinoless double beta ($0\nu\beta\beta$) decay, particularly short-range correlations among nucleons. The study of the pion potential is essential in this respect, as it represents the strong interaction counterpart of the neutrino potential, driving nucleon correlations in $0\nu\beta\beta$ decay. Numerical studies on pion potential have revealed an effective range of about 1 fm with slight dispersion around this value, confirming the short-range character of the MDCE process.
