Subgroup Of Finite Renormalizations, Conserving The NSVZ Relation In $\mathcal{N}=1$ SQED

Abstract

In supersymmetric quantum electrodynamics there is the exact relation between the expressed through the unrenormalized coupling gauge beta-function and the anomalous dimension of matter superfields. In the present report we describe the subgroup of general renormalization group transformations, conserving this relation exactly in all orders of the perturbation theory in terms of the renormalized coupling constant.
