The mere observation of the process proves the Majorana nature of neutrinos as well as the violation of the lepton number conservation, while the rate is a sensitive measure of the neutrino mass. The search for this effect at present concerns mainly the double β - decay. This paper describes...

the natural assumptions that massive neutrinos are Majorana particles and there are no unlikely fine-tuned cancellations among the contributions of the different neutrino masses, the results of solar neutrino experiments imply a lower bound for the effective Majorana mass in neutrinoless double-β decay...
-decay and/or 3 Hβ−decay experiments can provide on the lightest neutrino mass m 1 and on the CP-violation generated by the Majorana CP-violating phases α 21 and α 31 . We number the three neutrinos with definite mass ν j in such a way that their masses obey m 1 < m 2...

the resulting neutrino mass matrix yields a massless neutrino ν ′ e and two heavy Dirac neutrinos ψ ± with masses M 2 ± = M 2 ± M 4 −g 2 + u 2 (λ 2 v 2 +g 2 − u 2 ); M 2 = 1 2 M 2 +λ 2 v 2 +(g 2 + +g 2 − )u 2 . (2) In terms of th...
With the recent development of gauge theories, a growing interest has been focused on the nature of the neutrino. Since an observation of neutrinoless double beta (0uββ) decay would be practically the only possible evidence for the neutrino to be a Majorana particle, much effort has been ...
