One loop gauge couplings in AdS(5)

Abstract

We calculate the full 1-loop corrections to the low energy coupling of a bulk gauge boson in a slice of AdS(5) which are induced by generic 5-dimensional scalar, Dirac fermion, and vector fields with arbitrary Z(2)xZ(2)(') orbifold boundary conditions. In the supersymmetric limit, our results correctly reproduce the results obtained by an independent method based on 4-dimensional effective supergravity. This provides a nontrivial check of our results and assures the regularization scheme independence of the results.
