Texture Zeros and Majorana Phases of the Neutrino Mass Matrix
We present the generic formulas to calculate the ratios of neutrino masses and the Majorana phases of CP violation from the neutrino mass matrix with two independent vanishing entries in the flavor basis where the charged lepton mass matrix is diagonal. An order-of-magnitude illustration is given for seven experimentally acceptable textures of the neutrino mass matrix, and some analytical appro...
متن کاملTexture Zeros and Cp-violating Phases in the Neutrino Mass Matrix
We stress that specific texture zeros of lepton mass matrices, which might dynamically arise from a new kind of flavor symmetry, can help us to establish simple and testable relations between the lepton flavor mixing parameters and lepton mass ratios. We present a brief review of one-zero, two-zero and three-zero textures of the neutrino mass matrix. Their phenomenological consequences on neutr...
متن کاملSee-Saw Realization of the Texture Zeros in the Neutrino Mass Matrix
We study the see-saw realization of seven textures of the neutrino mass matrix, which were presented by Frampton, Glashow and Marfatia. Two of them (B1 and B2) are not realized in the see-saw mechanism without fine-tuning of parameters. We present some specific textures of the Dirac neutrino mass matrix and the right-handed Majorana neutrino one. In order to test these textures, we discuss the ...
متن کاملTexture of a Four–Neutrino Mass Matrix
We propose a simple texture of the neutrino mass matrix with one sterile neutrino along with the three standard ones. It gives maximal mixing angles for νe → νS and νμ → ντ oscillations or vice versa. Thus with only four parameters, this mass matrix can explain the solar neutrino anomaly, atmospheric neutrino anomaly, LSND result and the hot dark matter of the universe, while satisfying all oth...
متن کاملThe Elements of the Neutrino Mass Matrix: Allowed Ranges and Implications of Texture Zeros
We study the range of the elements of the neutrino mass matrix mν in the charged lepton basis. Neutrino-less double beta decay is sensitive to the ee element (the effective mass) of mν . We then analyze the phenomenological implications of single texture zeros. In particular, interesting predictions for the effective mass can be obtained, in the sense that typically only little cancellation due...
