| dc.description.abstract | We present a tribimaximal lepton mixing scheme where the neutrinoless double beta decay rate has a lower bound which correlates with the ratio alpha Delta m(sol)(2)/Delta m(atm)(2) well determined by current data, as well as with the unknown Majorana CP phase phi(12) characterizing the solar neutrino subsystem. For the special value phi(12) = pi/2 (opposite CP-sign neutrinos) the beta beta(0 nu) rate vanishes at tree level when Delta m(sol)(2)/Delta m(atm)(2) = 3/80, only allowed at 3 sigma. For all other cases the rate is nonzero, and lies within current and projected experimental sensitivities close to phi(12) = 0. We suggest two model realizations of this scheme in terms of A(4) x Z(2) and A(4) x Z(4) flavor symmetries. | |
