论文摘要
$μ\ leftrightarrowτ$对称性已被其对反应器和大气角度的预测所排除，但是，这种对称性的破坏可能会提供正确的值。因此，我们构建了一个不可降低的Lepton模型，其中混合源于$ \ MathBf {s} _ {4} \ otimes \ Mathbf {z} _ {z} _ {2} $ symix frok the symertry contrift the symix forcy the symix forcy the symix forcirtry forcirtry forcy the symix contrift the symix， II透明机制。作为主要结果，校正了反应器和大气角度，它们的值与倒立层次结构的实验数据非常吻合。此外，我们指出了大气角和反应堆之间的联系。在夸克部门，在某些假设下，广义的Fritzsch纹理形成夸克质量矩阵，以确保CKM矩阵值。
The $μ\leftrightarrow τ$ symmetry has been ruled out by its predictions on the reactor and atmospheric angles, nevertheless, a breaking of this symmetry might provide correct values. For that reason, we build a non-renormalizable lepton model where the mixings arise from the spontaneous breaking of the $\mathbf{S}_{4}\otimes \mathbf{Z}_{2}$ discrete group, subsequently the $μ\leftrightarrow τ$ symmetry is broken in the effective neutrino mass matrix, that comes from the type II see-saw mechanism. As main result, the reactor and atmospheric angles are corrected and their values are in good agreement with the experimental data for the inverted hierarchy. Furthermore, we point out a link between the atmospheric angle and reactor one. In the quark sector, under certain assumptions, the generalized Fritzsch textures shape to the quark mass matrices so that the CKM matrix values are guaranteed.
