论文摘要
带电瘦素的电偶极矩（EDM）是由Lepton部门的新的CP违规来源引起的。在本文中，我们在最小的Scotogenic模型中计算了带有两个Singlet Fermions的EDM，并考虑了中枢振荡数据的限制，这些模型用一个或两个三胞胎费米子而不是单身效费，而不是Singlet Fermions。我们表明，具有一个单线和一个三重速度的混合模型可以预测，在正常和倒立的中微子质量层次结构中，电子EDM大于其他模型。我们发现已经由电子EDM的当前上限排除了一些参数空间，并且可以通过未来的实验探索进一步的参数空间。
Electric dipole moments (EDMs) of charged leptons arise from a new source of CP violation in the lepton sector. In this paper, we calculate the EDMs of the charged leptons in the minimal scotogenic model with two singlet fermions, and the models extended with one or two triplet fermions instead of the singlet fermions, taking into account the constraints of the neutrino oscillation data, the charged lepton flavor violation and perturbative unitarity bound for the Yukawa couplings. We show that the hybrid model with one singlet and one triplet fermions predicts an electron EDM larger than the other models in both normal and inverted neutrino mass hierarchy. We find some parameter space has already been ruled out by the current upper bound of the electron EDM and further parameter space can be explored by future experiments.
