Abstract

Even after we have chosen a specific definition of the quantum-chromodynamic coupling constant (e.g., modified minimal subtraction or momentum-space subtraction) we are free to choose a definition of when we expand the coupling constant in powers of (lnQ2)-1. We discuss in detail a particular definition suggested by Abbott and argue that this definition does seem to provide an attractive means of fixing.
