One-loop divergences in non-Abelian supersymmetric theories regularized by BRST-invariant version of the higher derivative regularization

We consider a general non-abelian renormalizable $$ mathcal{n} $$ = 1 supersymmetric gauge theory, regularized by higher covariant derivatives without breaking the brst invariance, and calculate one-loop divergences for a general form of higher derivative regulator and of the gauge fixing term. it is demonstrated that the momentum integrals giving the one-loop β-function are integrals of double total derivatives independently of a particular choice of the higher derivative term. evaluating them we reproduce the well-known result for the one-loop β-function. also we find that the three-point ghost vertices with a single line of the quantum gauge superfield are not renormalized in the considered approximation.
