Description
Summary:We present one-loop contributions for with and in the extension of the standard model. In the phenomenological results, the signal strengths for at the Large Hadron Collider and for at future lepton colliders are analyzed in the physical parameter space for both the vector and chiral models. We found that the contributions from the neutral gauge boson to the signal strengths are rather small. Consequently, the effects will be difficult to probe at future colliders. However, the impacts of charged Higgs and CP-odd Higgs in the chiral model on the signal strengths are significant and can be measured with the help of the initial polarization beams at future lepton colliders.
