论文摘要
我们为中微子质量基质提供了一项完整的现象学和分析研究，其特征是两个消失的$ 2 \ times2 $字母。我们根据最近的实验数据更新了一个过去的结果。在15种可能的纹理中，我们发现7例可以容纳实验数据，而不是过去研究中的八个案例。我们还为基于非阿布莱恩（$ a_4 $或$ s_4 $）的可行纹理引入了很少的对称性实现，在II型SEESAW方案中的风味对称性。
We present a full phenomenological and analytical study for the neutrino mass matrix characterized by two vanishing $2\times2$ subtraces. We update one past result in light of the recent experimental data. Out of the fifteen possible textures, we find seven cases can accommodate the experimental data instead of eight ones in the past study. We also introduce few symmetry realizations for viable and nonviable textures based on non-abelian ($A_4$ or $S_4$) flavor symmetry within type II seesaw scenario.
