摘要：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 derived in the
models with discrete flavor symmetry. Only six textures among sixty ones are excluded by the
present experimental data. Since there are many textures which give similar predictions, the
textures are classified based on the numerical results. The neutrinoless double beta decay is
also examined in these textures. Our results suggest that there remain still rich structures of the
neutrino mass matrix in the phenomenological point of view.
