β-functions in large- Nf supersymmetric gauge theories
Abstract
We present calculations of the leading and O( {1}/{N f} 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( {1}/{N f} approximation displays an infrared fixed point in the conformal window {3}/{2}N c < N f < 3N c.
