论文摘要
我们在标准模型中评估了带电瘦素的电偶极力矩，其中Cabibbo-Kobayashi-Maskawa基质的复杂阶段是CP违规的唯一来源。我们首先证明，在夸克 - 格鲁恩级别上，由于Glashow-iliopoulos-Maiani机制，在所有扰动下，在所有扰动下的抑制倍数。然后，我们计算载体介子在一环水平上产生的HADRONIC长距离贡献。 $ |δs| = 1 $弱的辐射相互作用是使用该因素得出的，并且强相互作用是通过隐藏的局部对称框架建模的。我们发现，从该耐药机制获得的带电液体的电偶极矩比扰动的四环夸克 - 胶状过程大得多。
We evaluate the electric dipole moment of charged leptons in the standard model, where the complex phase of the Cabibbo-Kobayashi-Maskawa matrix is the only source of CP violation. We first prove that, at the quark-gluon level, it is suppressed by a factor of $m_b^2 m_c^2 m_s^2$ at all orders of perturbation due to the Glashow-Iliopoulos-Maiani mechanism. We then calculate the hadronic long distance contribution generated by vector mesons at one-loop level. The $|ΔS|=1$ weak hadronic interaction is derived using the factorization, and the strong interaction is modeled by the hidden local symmetry framework. We find that the electric dipole moments of charged leptons obtained from this hadronic mechanism are much larger than the perturbative four-loop level quark-gluon process, by several orders of magnitude.
