我们重新分析了马约拉纳中微子质量矩阵与两个纹理零，通过寻找可行的混合纹理，其中的非零矩阵元素有简单的比例。参考Frampton，Alfrehow和Marfatia的分类方案，我们发现用A1表示的质量矩阵允许比率和。对于纹理A2存在类似的比率。对于这两种混合纹理，例如，如果根据实验确定的质量平方差和计算三个混合角，则可以获得与数据的良好一致性。我们无法找到可行的混合纹理的基础上的质量矩阵不同的情况下A1和A2。
We reanalyze Majorana neutrino mass matrices with two texture zeros, by searching for viable hybrid textures in which the non-zero matrix elements of have simple ratios. Referring to the classification scheme of Frampton, Glashow and Marfatia, we find that the mass matrix denoted by A1 allows the ratios and . There are analogous ratios for texture A2. With these two hybrid textures, one obtains, for instance, good agreement with the data if one computes the three mixing angles in terms of the experimentally determined mass-squared differences and . We could not find viable hybrid textures based on mass matrices different from those of cases A1 and A2.
