Description

The scattering amplitude for the longitudinal weak bosons is investigated in the SU(3) gauge-Higgs unification as a function of the scattering energy, the Wilson line phase θH and the warp factor. The θH-dependence of the amplitude is quite different in the flat and the warped spacetimes. Generically the amplitude is enhanced for θH = O(1) in the warped case while it is almost independent of θH in the flat case. This indicates the tree-level unitarity is violated in the warped case at a lower scale than that in the flat case.
