1. 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. [...]

2. 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. [...]
