Abstract: We investigate the Lagrangian terms of scalar-gauge interactions in aweakly-coupled gauge theory beyond the ultraviolet momentum cutoff of modelswhere the collective symmetry breaking mechanism protects the Higgs masssquared against having quadratic divergence. We also propose a five-dimensionalmodel in which the gauge symmetry breaking is achieved by boundary conditionsconsistent with local gauge transformations. It is shown that the scalar-gaugeoperators in the two models differ in the absence of quadratic divergence.
