We present a comprehensive study of Higgs boson production associated with a neutrino pair at e+e− colliders (e+e−→hνν¯) at the next-to-leading-order accuracy in both the Standard Model and the two-Higgs-doublet model. We show that new physics effects from the extended Higgs sector can be probed through electroweak corrections, which lead to several percent deviations from the Standard Model...

There has been remarkable progress in recent years in the electric dipole moment (EDM) measurements of electron using paramagnetic atom or molecule. In a previous study, we calculated the contribution to the electron EDM induced by the CP-violating Yukawa interaction of electroweak multiplets at the three-loop level in effective field theory. We found that this contribution might reach the...

6. Large and Hidden CP Violation in the Complex Two-Higgs-Doublet Model

Jeonghyeon Song

We present a systematic study of large CP violation in the Complex Two-Higgs-Doublet Model with softly broken $Z_2$ symmetry, based on global scans of Type-I and Type-II realizations including theoretical consistency, collider data, and the stringent electron EDM constraint. We identify two qualitatively different CP-violating regimes: in Type-I, sizable gauge-sector CP violation is possible...
