Inspired by the recent development in determining the property of the observed Higgs boson, we explore the CP-violating (CPV) -{c}_{mathrm{CPV}}{hW}^{+mu nu}{tilde{W}}_{mu nu}^{-}/upsilon coupling in the Standard Model (SM) and beyond, where W±μν and {tilde{W}}^{pm mu nu} denote the W-boson field strength and its dual. To begin with, we show that the leading-order SM contribution to this CPV vertex appears at two-loop level. By summing over the quark flavor indices in the two loop integrals analytically, we can estimate the order of the corresponding Wilson coefficient to be {c}_{mathrm{CPV}}^{mathrm{SM}}sim mathcal{O}left({10}^{-23}right) , which is obviously too small to be probed at the LHC and planned future colliders. Then we investigate this CPV hW+W− interaction in two Beyond the Standard Model benchmark models: the left-right model and the complex 2-Higgs doublet model (C2HDM). Unlike what happens for the SM, the dominant contributions in both models arise at the one-loop level, and the corresponding Wilson coefficient can be as large as of mathcal{O} (10−9) in the former model and of mathcal{O} (10−3) for the latter. In light of such a large CPV effect in the hW+W− coupling, we also give the formulae for the leading one-loop contribution to the related CPV hZZ effective operator in the complex 2-Higgs doublet model. The order of magnitude of the Wilson coefficients in the C2HDM may be within reach of the high-luminosity LHC or planned future colliders.
