Abstract

The Higgs-boson production in association with a W-boson pair at e+ee^+e^- linear colliders is one of the important processes in probing the coupling between Higgs-boson and vector gauge bosons and discovering the signature of new physics. We describe the impact of the complete electroweak(EW) radiative corrections of O(αew){\cal O}(\alpha_{ew}) to this process in the standard model(SM) at the International Linear Collider(ILC), and investigate the dependence of the lowest-order(LO) and EW next-to-leading order(NLO) corrected cross sections on colliding energy s\sqrt{s} and Higg-boson mass. The LO and NLO EW corrected distributions of the invariant mass of W-boson pair and the transverse momenta of final WW- and Higgs-boson are presented. Our numerical results show that the relative EW radiative correction(δew\delta_{ew}) varies from -19.4% to 0.2% when mH=120GeVm_H=120 GeV and s\sqrt{s} goes up from 300GeV300 GeV to 1.2TeV1.2 TeV.
