This work is an extension of our previous work [Phys. Rev. Lett. 89, 131601 (2002)] which showed how to systematically calculate the high energy evolution of gauge couplings in compact AdS5 (five dimensional anti--de Sitter) backgrounds. We first directly compute the one-loop effects of massive charged scalar fields on the low energy couplings of a gauge theory propagating in the AdS background. It is found that scalar bulk masses (which generically are of the order of the Planck scale) enter only logarithmically in the corrections to the tree-level gauge couplings. As we pointed out previously, we show that the large logarithms that appear in the AdS one-loop calculation can be obtained within the confines of an effective field theory, by running the Planck brane correlator from a high UV matching scale down to the TeV scale. This result exactly reproduces our previous calculation, which was based on AdS--conformal field theory duality. We also calculate the effects of scalar fields satisfying nontrivial boundary conditions (relevant for orbifold breaking of bulk symmetries) on the running of gauge couplings.
