We numerically estimate a scale Λ at which tree-level unitarity is violated in the SO(5)xU(1) gauge-Higgs unification model by evaluating amplitudes for scattering of the longitudinal W bosons. The scattering amplitudes take larger values in the Randall-Sundrum warped spacetime than in the flat spacetime. We found that Λ = 1.3 mKK in the warped spacetime, and Λ = 140 mKK in the flat spacetime, where mKK is the Kaluza-Klein mass scale. |
