Half-life of Xe for neutrinoless double- decay calculated with effective axial-vector current coupling unified for two-neurtino and neutrinoless double- decay modes
J. Terasaki, O. Civitarese
The upper limit on the mass of the Majorana neutrino, extracted from the limits on the nonobservation of the neutrinoless double- () decay, is hampered by uncertainties in…

Effects of perturbation for transition operator of double- decay on nuclear matrix element, effective axial-vector current coupling, and half-life
J. Terasaki, O. Civitarese
We calculate the nuclear matrix element (NME), effective axial-vector current coupling , and half-life of the double- () decay using the transition operato…

Vertex correction to nuclear matrix elements of double- decays
Jun Terasaki
The predicted neutrinoless double- () decay is the crucial phenomenon to prove the existence of the Majorana neutrino, which gives a foundation to leptogenesis to explain…
