Two-loop renormalization of the matter superfields and finiteness of $\mathcal{N}=1$ supersymmetric gauge theories regularized by higher derivatives

Alexander Kazantsev, Konstantin Stepanyantz

The two-loop anomalous dimension of the chiral matter superfields is calculated for a general $\mathcal{N}=1$ supersymmetric gauge theory regularized by higher covariant derivatives.…
