One loop gauge couplings inAdS5

We calculate the full 1-loop corrections to the low energy coupling of a bulk gauge boson in a slice of ${\mathrm{AdS}}_5$ which are induced by generic 5-dimensional scalar, Dirac fermion, and vector fields with arbitrary $Z_2\times Z_2^{\prime }$ 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.
