On the Beta Function in Supersymmetric Gauge Theories
arXiv:hep-th/9902162 · doi:10.1016/S0370-2693(99)00454-2
Abstract
We re-examine perturbative and nonperturbative aspects of the beta function in N=1 and N=2 supersymmetric gauge theories, make comments on the recent literature on the subject and discuss the exactness of several known results such as the NSVZ beta function.
