论文摘要
我们介绍了复杂的两-higgs Doublet模型中电子EDM的第一个完整的两个循环计算。我们通过证明对量规参数$ξ$在背景字段量规和't Hooft $r_ξ$仪表中的分析取消来确认量规不依赖性。我们还研究了在脱钩极限附近的电子EDM的行为，并通过匹配有效的田间理论来确定短和长距离的贡献。与复杂的两-higgs Doublet模型中电子EDM的早期研究相比，我们注意到几个地方的分歧，并在可能的情况下提供诊断。我们还提供光夸克EDM的表达式。
We present the first complete two loop calculation of the electron EDM in the complex two-Higgs doublet model. We confirm gauge-independence by demonstrating analytic cancellation of the gauge parameter $ξ$ in the background field gauge and the 't Hooft $R_ξ$ gauge. We also investigate the behavior of the electron EDM near the decoupling limit, and determine the short- and long-distance contributions by matching onto an effective field theory. Compared with earlier studies of the electron EDM in the complex two-Higgs doublet model, we note disagreements in several places and provide diagnoses where possible. We also provide expressions for EDMs of light quarks.
