Abstract
We examine trilinear gauge boson couplings (TGCs) in the context of the SU (3)W ⊗ U (1) � gauge–Higgs unification scenario. The TGCs play important roles in probes of the physics beyond the standard model, since they are highly restricted by the experiments. We discuss the mass spectrum of the neutral gauge boson with brane-localized mass terms carefully and find that the TGCs and ρ parameter may deviate from standard model predictions. Finally, we put a constraint on these observables and discuss the possible parameter space.
