论文摘要
我们在标准模型（SM）的扩展中检查了Lepton偶极矩，其中包含仅与第二代Sm lept子相对的矢量样瘦素。该模型自然会为MUON $ G-2 $和MUON电动偶极矩（EDM）做出相当大的贡献。该模型的一个特征是，由于循环中存在新的矢量样瘦素，因此在两循环水平上还诱导了相当大的电子EDM。我们发现可以解释MUON $ G-2 $异常的参数区域，并且与来自电子EDM的实验约束和Higgs Decay $ H \rightArrowμ^{+}μ^{ - } $一致。生成的EDM可以大于$ O（10^{ - 22}）〜E \ CDOT \ CDOT \ CDOT \ MATHRM {cm} $，对于EDM的EDM测量，可以分别对电子的EDM衡量EDM测量，分别对电子进行了探测。
We examine the lepton dipole moments in an extension of the Standard Model (SM), which contains vector-like leptons that couple only to the second-generation SM leptons. The model naturally leads to sizable contributions to the muon $g-2$ and the muon electric dipole moment (EDM). One feature of this model is that a sizable electron EDM is also induced at the two-loop level due to the existence of new vector-like leptons in the loops. We find parameter regions that can explain the muon $g-2$ anomaly and are also consistent with the experimental constraints coming from the electron EDM and the Higgs decay $h\rightarrow μ^{+}μ^{-}$. The generated EDMs can be as large as $O(10^{-22})~e \cdot \mathrm{cm}$ for the muon and $O(10^{-30})~e \cdot \mathrm{cm}$ for the electron, respectively, which can be probed in future experiments for the EDM measurements.
