Abstract

The precise investigation of the W+WZ0W^+ W^-Z^0 production at the e+ee^+e^- International Linear Collider(ILC) is of crucial importance in probing the couplings between massive vector gauge bosons and discovering the signature of new physics beyond the standard model(SM). We study the full one-loop EW effects on the observables, such as, the total cross section, the differential cross section of the invariant mass of WW-pair, the distribution of the angle between WW-pair, the production angle distributions of WW- and Z0Z^0-boson, the distributions of the transverse momenta of final WW- and Z0Z^0-boson, and the forward-backward charge asymmetry of WW^--boson. Our numerical results show that the EW relative correction to the total cross sections(δew\delta_{ew}) varies from -18.9% to -5.7% when mH=120GeVm_H=120 GeV and s\sqrt{s} goes up from 300GeV300 GeV to 1TeV1 TeV.
