W and Z boson pair production at electron-positron colliders in gauge-Higgs unification

Popis výsledku v původním jazyce

We examine W and Z boson pair production processes at electron-positron collider experiments in the SU(3)_C times SO(5)_W times U(1)_X gauge-Higgs unification (GHU) model. We find that the deviation of the total cross section for the e^-e^+ -> W^-W^+ process from the Standard Model (SM) in the GHU model with parameter sets, which are consistent with the current experiments, is about 0.5% to 1.5% and 0.6% to 2.2% for sqrt{s} = 250 GeV and 500 GeV, respectively, depending on the initial electron and positron polarization. We find that for the e^-e^+ -> ZZ process the deviation from the SM in the GHU model is at most 1%. We find that unitarity bound for the e^-e^+ -> W^-W^+ process is satisfied in the GHU model as in the SM, as a consequence of the relationship among coupling constants.
