论文摘要
在MSSM扩展的框架内，具有本地测量的Baryon和Lepton数字（BLMSSM），我们计算MUON异常磁性偶极矩（MDM）和Lepton $（E，μ，τ）$电动偶极矩（EDM），并讨论了Muon Mdm和Lepton Edm的依赖性参数，并依赖于群众的参数。在许多参数中，$ \tanβ$，〜$ g_l $，〜$ m_l $和$μ_h$是$ a^{bl}_μ$的更敏感参数。考虑到实验限制，我们的$ a^{bl} _ $的最佳数值结果约为$ 2.5 \ times 10^{ - 9} $，可以很好地补偿实验数据和标准模型（SM）预测之间的出发。 BLMSSM中违反阶段的CP比MSSM中的阶段更多，包括新参数$θ_{μ_l} $和$θ_{l} $。他们可以做出大量贡献，这些贡献在探索CP违规的根源和SM以外的新物理学方面起着重要作用。
In the framework of the MSSM extension with local gauged baryon and lepton numbers (BLMSSM), we calculate the muon anomalous magnetic dipole moment (MDM) and lepton $(e, μ, τ)$ electric dipole moment (EDM), and discuss how the muon MDM and lepton EDM depend on the parameters within the mass insertion approximation. Among many parameters, $\tanβ$,~$g_L$,~$m_L$ and $μ_H$ are more sensitive parameters for $a^{BL}_μ$. Considering the experimental limitations, our best numerical result of $a^{BL}_μ$ is around $2.5 \times 10^{-9}$, which can well compensate the departure between the experiment data and Standard Model (SM) prediction. The CP violating phases in BLMSSM are more than those in the MSSM, including new parameters $θ_{μ_L}$ and $θ_{L}$. They can give large contributions, which play an important role in exploring the source of CP violation and probing new physics beyond SM.
