Probing Short-range Correlations in Heavy-ion Double Charge Exchange Reactions

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 the 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.
