唯象二零中微子织构的阿贝尔实现

Abelian realization of phenomenological two-zero neutrino textures

R. Gonzalez Felipe, H. Serodio

摘要:

在解释中微子质量平方差和轻子混合的尝试中,具有零织构的轻子质量矩阵被广泛研究。在荷电轻子质量矩阵为对角矩阵的弱基中,各种带两个零点的中微子质量矩阵已被证明与现有的实验数据一致。利用正则和Smith规范形方法,我们构造了这些唯象二零中微子织构的最小阿贝尔对称实现。这些对称性的上下文中的跷跷板机制马约拉纳中微子质量的实施进行了讨论。

英文摘要:

In an attempt at explaining the observed neutrino mass-squared differences and leptonic mixing, lepton mass matrices with zero textures have been widely studied. In the weak basis where the charged lepton mass matrix is diagonal, various neutrino mass matrices with two zeros have been shown to be consistent with the current experimental data. Using the canonical and Smith normal form methods, we construct the minimal Abelian symmetry realizations of these phenomenological two-zero neutrino textures. The implementation of these symmetries in the context of the seesaw mechanism for Majorana neutrino masses is also discussed.
