Název v původním jazyce

Two neutrino double-beta decay and effective axial-vector coupling constant

Popis výsledku v původním jazyce

The theoretical and experimental study of the two-neutrino double-beta decay (2v beta beta-decay) is of crucial importance for reliable calculation of matrix elements governing the neutrinoless double-beta decay (0v beta beta-decay). That will allow to determine masses of neutrinos once the 0v beta beta-decay, which occurs if the neutrino is a massive Majorana particle and the total lepton number is not conserved, will be observed. Experiments studying the 2v beta beta-decay are currently approaching a qualitatively new level, where high-precision measurements are performed not only for half-lives but for all other observables of the process. In this context an improved formula for the 2v beta beta-decay is presented. Further, a novel approach for determining the effective axial-vector coupling constant is proposed.
