Abstract

We present calculations of the leading and O(1/Nf)O(1/N_f) terms in a large-NfN_f expansion of the β\beta-functions and anomalous dimensions for various supersymmetric gauge theories, including supersymmetric QCD. In the case of supersymmetric QCD, we show that our O(1/Nf)O(1/N_f) approximation displays an infra-red fixed point in the conformal window 3Nc/2<Nf<3Nc3N_c/2 < N_f < 3N_c.
