论文摘要
我们讨论了CP违规的效果，在一般两-higgs-doublet模型的对齐场景中，其中希格斯的潜力和Yukawa的相互作用提供了其他CP侵略阶段。为了避免危险的味道变化中性电流，对Yukawa的相互作用进行了对齐。还对希格斯电势进行对准，以使最轻的希格斯玻色子的耦合常数被确定为质量为125 GEV的发现的希格斯玻色子，与标准模型的质量相同。通常，由Yukawa相互作用和HIGGS电位源自CP侵略阶段，受到电偶极矩（EDM）的当前数据的强烈限制。发现在我们的情况下，CP违规的两个来源的贡献可能是破坏性的，因此，即使每个CP侵略阶段都大，它们的总贡献也可以满足EDM结果。可以通过查看附加希格斯玻色子衰变产生的颗粒的角度分布来测试这种较大的CP侵略阶段。
We discuss the effect of CP violation in the aligned scenario of the general two-Higgs-doublet model, in which the Higgs potential and the Yukawa interaction provide additional CP-violating phases. An alignment is imposed to the Yukawa interaction in order to avoid dangerous flavor changing neutral currents. The Higgs potential is also aligned such that the coupling constants of the lightest Higgs boson, which is identified as the discovered Higgs boson with the mass of 125 GeV, are the same as those of the standard model. In general, CP-violating phases originated by the Yukawa interaction and the Higgs potential are strongly constrained by the current data for the electric dipole moment (EDM). It is found that in our scenario contributions from the two sources of CP violation can be destructive and consequently their total contribution can satisfy the EDM results, even when each CP-violating phase is large. Such a large CP-violating phase can be tested at collider experiments by looking at the angular distributions of particles generated by the decays of the additional Higgs bosons.
