Three-loop contribution of the Faddeev-Popov ghosts to the $\beta$-function of $\mathcal{N}=1$ supersymmetric gauge theories and the NSVZ relation

M. D. Kuzmichev, N. P. Meshcheriakov, S. V. Novgorodtsev +2

We find the three-loop contribution to the $\beta$-function of $\mathcal{N}=1$ supersymmetric gauge theories regularized by higher covariant derivatives produced by the supergraphs contai…
