Abstract
Abstract We apply the functional renormalization group approach to a $$\mathcal {N}=1$$ N = 1 supersymmetric gauge model with one chiral superfield coupled to a vector U(1) superfield. We find that the nonrenormalization theorem still works at leading order in the supercovariant derivative expansion of the fields. We also find the beta functions and we study the behavior of its fixed points in the local potential approximation. Regulators are also discussed.
