Subtleties in the beta-function calculation of N=1 supersymmetric gauge theories

We investigate some peculiarities in the calculation of the two-loop beta function of N = 1 supersymmetric models which are intimately related to the so-called “anomaly puzzle”. There is an apparent paradox when the computation is performed in the framework of the covariant derivative background fie...
