2. A class of the NSVZ renormalization schemes for N=1 SQED / Goriachuk, I.O. ; Kataev, A.L. ; Stepanyantz, K.V.
For the N=1 supersymmetric electrodynamics we investigate renormalization schemes in which the NSVZ equation relating the β -function to the anomalous dimension of the matter superfields is valid in all loops. [...]

4. New form of the NSVZ relation at the two-loop level / Shakhmanov, V.Yu. ; Stepanyantz, K.V.
Recently the exact NSVZ β -function was rewritten in the form of a relation between the β -function and the anomalous dimensions of the quantum gauge superfield, of the Faddeev–Popov ghosts, and of the matter superfields. [...]

5. The Adler D -function for N=1 SQCD regularized by higher covariant derivatives in the three-loop approximation / Kataev, A.L. ; Kazantsev, A.E. ; Stepanyantz, K.V.
We calculate the Adler D -function for N=1 SQCD in the three-loop approximation using the higher covariant derivative regularization and the NSVZ-like subtraction scheme. [...]

We study the one-loop effective action for 6 D , N=(1,0) supersymmetric Yang–Mills (SYM) theory with hypermultiplets and 6 D , N=(1,1) SYM theory as a subclass of the former, using the off-shell formulation of these theories in 6 D , N=(1,0) harmonic superspace. [...]

7. Three-loop NSVZ relation for terms quartic in the Yukawa couplings with the higher covariant derivative regularization / Shakhmanov, V.Yu. ; Stepanyantz, K.V.
We demonstrate that in non-Abelian N=1 supersymmetric gauge theories the NSVZ relation is valid for terms quartic in the Yukawa couplings independently of the subtraction scheme if the renormalization group functions are defined in terms of the bare couplings and the theory is regularized by higher covariant derivatives. [...]

10. Non-renormalization of the Vc¯c -vertices in N=1 supersymmetric theories / Stepanyantz, K.V.
Using the Slavnov–Taylor identities we prove that the three-point ghost vertices with a single line of the quantum gauge superfield are not renormalized in all loops in N=1 supersymmetric gauge theories. [...]
