Gauge coupling renormalization in orbifold field theories

Abstract

We investigate the gauge coupling renormalization in orbifold field theory preserving 4-dimensional N = 1 supersymmetry in the framework of 4-dimensional effective supergravity. As a concrete example, we consider the 5-dimensional Super-Yang-Mills theory on a slice of AdS(5). In our approach, one-loop gauge couplings can be determined by the loop-induced axion couplings and the tree level properties of 4-dimensional effective supergravity which are much easier to be computed.
