我们提出了数值和全面的分析的60个混合结构的中微子，其中有一个平等的矩阵元素和一个零。这些纹理可能来自离散对称性。在60种织构中，只有6种被目前的实验数据排除在外。由于有许多纹理给出类似的预测，纹理分类的基础上的数值结果。无中微子双β衰变也检查在这些纹理。我们的结果表明，从唯象的观点来看，中微子质量矩阵仍然具有丰富的结构。
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 from the discrete 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.
