Uncertainties in nuclear transition matrix elements for neutrinoless decay II: the heavy Majorana neutrino mass mechanism
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 heavy
Majorana neutrino for the transition of neutrinoless
double beta decay of Zr, Zr, Mo, Mo, Ru,
Pd, Te and Nd isotopes in the PHFB model are
estimated to be around 25%. Excluding the nuclear transition matrix elements
calculated with Miller-Spenser parametrization of Jastrow short range
correlations, the uncertainties are found to be 10%-15% smaller
