Abstract
We investigate the Crewther relation at high loop order in a variety of renormalization schemes and gauges. By examining the properties of the relation in schemes other than modified minimal subtraction (MS¯) at the fixed points of quantum chromodynamics we propose a generalization of the Crewther relation that extends the MS¯ construction of Broadhurst and Kataev. A derivation based on the properties of the renormalization group equation is provided for the generalization which is tested in various scenarios.
