摘要：

Employing the projected-Hartree-Fock-Bogoliubov (PHFB) model in conjunction with four different parametrizations of pairing plus multipolar effective two-body interaction and three different parametrizations of Jastrow short-range correlations, nuclear transition matrix elements for the neutrinoless double-beta decay of Zr-94,Zr-96, Mo-100, (110)pd, Te-128,Te-130 and Nd-150 isotopes are calculated within mechanisms involving light Majorana neutrino mass and right-handed current. Statistically, model specific uncertainties in sets of twelve nuclear transition matrix elements are estimated by calculating the averages along with the standard deviations. For the considered nuclei, the most stringent extracted on-axis limits on the effective light Majorana neutrino mass < m(nu)>, the effective weak coupling of right-handed leptonic current with right-handed hadronic current <lambda >, and the effective weak coupling of right-handed leptonic current with left-handed hadronic current <eta > from the observed limit on half-life T-1/2(0 nu) of Te-130 isotope are 0.33 eV, 4.57 x 10(-7) and 4.72 x 10(-9), respectively.
