Comment on Kaluza-Klein Spectrum of Gauge Fields in the Bigravity Model

Abstract

We study behavior of bulk gauge field in the bigravity model in which two positive tension $Ad{S}_4$ branes in $Ad{S}_5$ bulk are included. We solve the equations of motions for Kaluza-Klein modes and determine the mass spectrum. It is shown that unlike the case of graviton, we find no ultralight Kaluza-Klein modes in the spectrum.
