N. Haba, K.-y. Oda, R. Takahashi. Diagonal Kaluza–Klein Expansion Under Brane Localized Potential. Acta Phys. Pol. B 41, 1291 (2010).

We clarify and study our previous observation that, under a compactification with boundaries or orbifolding, vacuum expectation value of a bulk scalar field can have different extra-dimensional wave-function profile from that of the lowest Kaluza–Klein mode of its quantum fluctuation, under presence of boundary-localized potentials which would be necessarily generated through renormalization group running. For concreteness, we analyze the Universal Extra Dimension model compactified on orbifold S1/Z2, with brane-localized Higgs potentials at the orbifold fixed points. We compute the Kaluza–Klein expansion of the Higgs and gauge bosons in an Rξ-like gauge by treating the brane-localized potential as a small perturbation. We also check that the ρ parameter is not altered by the brane localized potential.
