摘要：
We analyze CP-violating effects in both electric dipole moment (EDM) measurements and future analyses at the Large Hadron Collider (LHC) assuming a two-Higgs-doublet model (2HDM) with "soft" CP violation. Our analysis of EDMs and current LHC constraints shows that, in the case of Type 11 and Type III 2HDMs, an O(0.1) CP-violating phase in the Yukawa interaction between H-1 (the 125 GeV Higgs boson) and fermions is still allowed. For these scenarios, we study CP-violating effects in the neutron EDM and (tt) over barH(1) production at the LHC. Our analysis shows that such an O(0.1) CP-violating phase can be easily confirmed or excluded by future neutron EDM tests, with LHC data providing a complementary cross-check.
