  We consider the possibility of gauge bosons living in the recently proposed
five-dimensional theory with localized gravity. We study the mass spectrum of
the Kaluza-Klein (KK) excitations of the gauge fields and calculate their
couplings to the boundaries of the fifth dimension. We find a different
behaviour from the case of the graviton. In particular, we find that the
massless mode is not localized in the extra dimension and that the KK
excitations have sizeable couplings to the two boundaries. We also discuss
possible phenomenological implications for the case of the standard model gauge
bosons.
