Embedding the Texture of the Neutrino Mass Matrix into the MaVaNs Scenario

Original · EN

We have embedded the texture of the neutrino mass matrix with three families into the MaVaNs scenario. We take the power-law potential of the acceleron field and a typical texture of active neutrinos, which is derived by the D₄ symmetry and predicts the maximal mixing of the atmospheric neutrino and the vanishing Uₑ₃. The effect of couplings among the dark fermion and active neutrinos are studied by putting the current cosmological data and the terrestrial neutrino experimental data. It is found that the neutrino flavor mixings evolve as well as the neutrino masses. Especially, Uₑ₃ develops into the non-vanishing one and θatm deviates from the maximal mixing due to couplings among the dark fermion and active neutrinos.
