Relation between two-point Green functions of $\mathcal{N}=1$ SQED with $N_f$ flavors, regularized by higher derivatives, in the three-loop approximation

A. E. Kazantsev, K. V. Stepanyantz

We verify the identity which relates the two-point Green functions of $\mathcal{N}=1$ SQED with $N_f$ flavors, regularized by higher derivatives, by explicit calculations in the three…
