论文摘要
我们使用$ S_4 $风味对称性的超对称额外U（1）模型。风味对称性不仅可以稳定质子，还可以抑制变化的过程，而不会提高超对称性破裂量表。味道对称性破裂后，Yukawa的层次结构是由Froggatt-Nielsen机制实现的。轴线暗物质的相关Peccei-Quinn量表：$ \ frac {f_a} {m_p} \ sim 10^{ - 5} $ account for Small up quark质量。 MUON质量尺度：$ \ frac {m_μ} {m_w} \ sim 10^{ - 3} $与$ O（10^{ - 6}）$右手中微子的质量变性有关，我们可以从中确定Baryon Andrinos Masse的相关标度的Baryon Antryon Antryon Antryon Ancymememmetry as-Memmetry as-MememeTry as te tev的相关标度。由于存在额外的希格斯诺诺斯，因此chargino-sneutrino同时贡献了穆恩异常磁矩的差异以及标准模型预测和观察值之间的电子差异。
We study supersymmetric extra U(1) model with $S_4$ flavor symmetry. The flavor symmetry not only stabilizes proton but also suppresses the flavor changing processes without raising the supersymmetry breaking scale. After the flavor symmetry is broken, the Yukawa hierarchy is realized by the Froggatt-Nielsen mechanism. The relevant Peccei-Quinn scale for axion dark matter: $\frac{f_a}{M_P}\sim 10^{-5}$ accounts for small up quark mass. The muon mass scale: $\frac{m_μ}{M_W}\sim 10^{-3}$ is related to the $O(10^{-6})$ mass degeneracy of right-handed neutrinos, from which we can identify the relevant scale of right-handed neutrino mass for baryon asymmetry of the Universe as TeV. Due to the existence of the extra higgsinos, the discrepancies of the anomalous magnetic moments of the muon and the electron between the standard model predictions and the observations are explained by the chargino-sneutrino contributions simultaneously.
