Gauge coupling renormalization in AdS5
We present the relation of the 4-dimensional low energy gauge coupling and the 5-dimensional fundamental gauge coupling of bulk gauge boson in a slice of AdS5, which is orbifolded byZ2 ×Z′2. We calculate the full 1-loop corrections for the case of generic 5-dimensional scalar, Dirac fermion, and vector fields with arbitraryZ2×Z′2. For the supersymmetric case, we obtain the result more easily by using the 4-dimensional effective supergravity approach.
