β-functions in large-Nf supersymmetric gauge theories Original Research Article

We present calculations of the leading and O(1Nf terms in a large-Nf expansion of the β-functions and anomalous dimensions for various supersymmetric gauge theories, including supersymmetric QCD. In the case of supersymmetric QCD, we show that our O(1Nf approximation displays an infrared fixed point in the conformal window 32Nc < Nf < 3Nc.
