Supersymmetric calculations with component fields in differential renormalization

Abstract

Two applications of the method of differential renormalization to supersymmetric gauge theories are reviewed. The photon propagator in supersymmetric QED is renormalized at one loop and the first supergravity contributions to the anomalous magnetic moment of a charged lepton are obtained.
