New form of the exact NSVZ $\beta$-function: the three-loop verification for terms containing Yukawa couplings

A. E. Kazantsev, V. Yu. Shakhmanov, K. V. Stepanyantz

We investigate a recently proposed new form of the exact NSVZ $\beta$-function, which relates the $\beta$-function to the anomalous dimensions of the quantum gauge superfield, of the Fadde…
