Abstract We investigate dimension-five Lorentz-violating (LV) nonminimal interactions in the electroweak sector, in connection with the possible generation of electric dipole moment (EDM), weak electric dipole moment (WEDM), magnetic dipole moment (MDM) and weak magnetic dipole moment (WMDM) for leptons. These couplings are composed of the physical fields in the Standard Model and LV tensors of ranks ranging from 1 to 4. The CPT-odd couplings do not generate EDM behavior nor provide the correct MDM signature, while the CPT-even ones are compatible with EDM and MDM behavior, being subject to improved constraining. Tau lepton experimental data is used to constrain the WEDM and WMDM couplings to the level of 10 − 4 ( GeV ) − 1 , whereas electron MDM and EDM data are employed to improve constraints to the level of 10 − 10 ( GeV ) − 1 and 10 − 16 ( GeV ) − 1 , respectively.

限制电弱扇区中的 EDM 和 MDM 轻子五维相互作用

摘要 我们研究了电弱扇区中五维洛伦兹违反 (LV) 非最小相互作用，这与电偶极矩 (EDM)、弱电偶极矩 (WEDM)、磁偶极矩 (MDM) 和弱磁的可能产生有关。轻子的偶极矩 (WMDM)。这些耦合由标准模型中的物理场和等级范围从 1 到 4 的 LV 张量组成。 CPT 奇耦合不生成 EDM 行为，也不提供正确的 MDM 签名，而 CPT 偶耦合与 EDM 兼容和 MDM 行为，受到改进的约束。Tau 轻子实验数据用于将 WEDM 和 WMDM 耦合限制在 10 − 4 ( GeV ) − 1 的水平，
