论文摘要
我们考虑$ u（1）_ {l_μ-l_τ} $扩展的左右对称仪表理论，其中中微质量是通过反seesaw机制生成的。在此模型中，MUON $（G-2）$异常由$ z_ {μτ} $的中介（$ u（1）_ {l_μ-l_τ} $ symemertry的调解。该模型的对称性要求光中微子质量基质具有特定的两零纹理，从而导致最小中微子质量的非平凡约束。此外，该模型预测可观察到的充电Lepton风味违反$μ-τ$扇区。
We consider an $U(1)_{L_μ-L_τ}$ extended left-right symmetric gauge theory where the neutrino masses are generated through inverse seesaw mechanism. In this model the muon $(g-2)$ anomaly is accounted for by the mediation of $Z_{μτ}$, the gauge boson of $U(1)_{L_μ- L_τ}$ symmetry. The symmetries of the model require the light neutrino mass matrix to have a particular two-zero texture, which leads to non-trivial constraints in the minimum neutrino mass. In addition, the model predicts observable charged lepton flavor violation in $μ-τ$ sector.
