Information About Author:

Using Scwinger-Dyson equation we prove that the beta-function for N = 1 supersymmetric electrodynamics is given by integrals of double total derivatives. This allows to calculate one of the loop integrals and obtain the exact NSVZ beta-function, which relates the beta-function and the anomalous dimension of the matter superfield.

Keywords: supersymmetry, supergraphs, NSVZ beta-function
