Four-loop verification of an algorithm for summing Feynman diagrams in
the $N{=}1$ supersymmetric electrodynamics

Abstract:
By calculating some four-loop diagrams in the $N{=}1$ supersymmetric
electrodynamics regularized by higher derivatives, we verify a method for
summing Feynman diagrams based on using Schwinger–Dyson equations and Ward
identities. In particular, for the diagrams considered, we prove the
correctness of an additional identity for Green's functions not reduced to
the gauge Ward identity.
Keywords:
supersymmetry, Ward identity, higher covariant derivatives.
