Role of short range correlations on nuclear matrix elements of neutrinoless double beta decay

Abstract

Employing four different parametrization of the pairing plus multipolar type of effective two-body interaction and three different parametrizations of Jastrow-type of short range correlations, the uncertainties in the nuclear transition matrix elements due to the exchange of light as well as heavy Majorana neutrino for the 0+ → 0+ transition of neutrinoless positron β β decay are estimated in the PHFB model.
