Hybrid Textures of Neutrino Mass Matrix
S. Kaneko, H. Sawanaka, M. Tanimoto
We present analyses of the sixty hybrid textures of neutrino mass matrix, which have an equality of matrix elements and one zero. These textures are possibly derived in the models…
Mu-tau antisymmetry and neutrino mass matrices
Walter Grimus, Satoru Kaneko, Luis Lavoura +2
Using the seesaw mechanism and a discrete symmetry, we construct a class of models for the neutrino mass matrix where the inverse of that matrix is the sum of a mu-tau antisymmetri…
Embedding the Texture of the Neutrino Mass Matrix into the MaVaNs Scenario
Mizue Honda, Ryo Takahashi, Morimitsu Tanimoto
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…
Model of Mass Varying Neutrinos in SUSY
Ryo Takahashi, Morimitsu Tanimoto
We discuss the mass varying neutrino scenario in the supersymmetric theory. In the case of the model with the single superfield, one needs the soft SUSY breaking terms or the t…
Cosmological Family Asymmetry and CP violation
T. Fujihara, S. Kaneko, S. Kang +3
We discuss how the cosmological baryon asymmetry can be achieved by the lepton family asymmetries of heavy Majorana neutrino decays and they are related to CP violation in neutrino…
Prediction of Ue3 and \cos 2θ_23 from discrete symmetry
Morimitsu Tanimoto
We discuss the question why the mixing is small. The natural answer is in some symmetric limit, in which two large mixings are realized. It is possible to force…
Hybrid Textures of Neutrinos
Satoru Kaneko, Hideyuki Sawanaka, Morimitsu Tanimoto
We present numerical and comprehensive analyses of the sixty hybrid textures of neutrinos, which have an equality of matrix elements and one zero. These textures are possibly deriv…
