Abstract: Using Schwinger–Dyson equations and Ward identities in the $N=1$ supersymmetric electrodynamics regularized by higher derivatives, we find that we can calculate some contributions to the two-point Greens function of the gauge field and to the $\beta$-function exactly in all orders of the perturbation theory. We use the results to investigate the anomaly puzzle in the considered theory.

Keywords: supersymmetry, regularization, higher covariant derivative, anomaly puzzle.
