在希格斯扇区发现CP破坏效应将构成超越标准模型的物理学无可争议的标志。我们推导出的CP违反希格斯玻色子耦合的顶部和底部夸克以及τ轻子从低能量范围内的电偶极矩的约束，在必要时，smilming大的电子。目前和未来的预测的敏感性和比较与LHC的限制。即使希格斯玻色子只与第三代费米子耦合，在未来也可能出现非平凡的约束。
Discovering CP-violating effects in the Higgs sector would constitute an indisputable sign of physics beyond the Standard Model. We derive constraints on the CP-violating Higgs-boson couplings to top and bottom quarks as well as to tau leptons from low-energy bounds on electric dipole moments, resumming large logarithms when necessary. The present and future projections of the sensitivities and comparisons with the LHC constraints are provided. Non-trivial constraints are possible in the future, even if the Higgs boson only couples to the third-generation fermions.
