论文摘要
我们对Majorana中微子质量矩阵的纹理结构进行系统研究，鉴于最近的中微子振荡数据，具有两个纹理零和两个非零矩阵元素之间的平等。在42个可能的纹理中，发现只有八个纹理与3 $σ$ c.l.当前的实验数据兼容。在这些现象学上可行的纹理中，六个遵循正常的质量顺序，而剩余的两个则满足了中微子质谱的倒数质量顺序。在数值分析中，我们对所有可行模式的可能空间进行了扫描。我们介绍了每种允许的模式对三个混合角度（太阳能，反应堆和大气），Leptonic CP侵略，中微子质量尺度和中性元双β衰变的含义，表明振荡参数之间存在很强的相关性。还提出了其中一种可行纹理的对称性实现。
We perform a systematic investigation of the texture structures of Majorana neutrino mass matrix $M_ν$ having two texture zeros and an equality between two nonzero matrix elements, in the light of recent neutrino oscillation data. Among forty-two possible textures, it is found that only eight textures are compatible with the current experimental data at 3$σ$ C.L. Out of these phenomenologically viable textures, six follow normal mass ordering while remaining two satisfy the inverted mass ordering of neutrino mass spectrum. In the numerical analysis, we carry out a scan over the possible space of all viable patterns. We present the implications of each allowed patterns for three mixing angles (solar, reactor and atmospheric), leptonic CP-violation, neutrino mass scale and the neutrinoless double beta decay indicating strong correlations between oscillation parameters. The symmetry realization of one of the viable textures is also presented.
