Abstract:
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-β decay of 94,96Zr, 100Mo, 110Pd,
128,130Te and 150Nd 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 < mν >,
the effective weak coupling of right-handed leptonic current with right-handed hadronic
current < λ >, and the effective weak coupling of right-handed leptonic current with
left-handed hadronic current < η > from the observed limit on half-life T
0ν
1/2
of 130Te
isotope are 0.33 eV, 4.57 × 10−7 and 4.72 × 10−9
, respectively.
