Renormalization scheme invariant perturbative approach as an alternative to the conventional perturbation theory
We develop a formalism for resolving the renormalization scheme (RS) ambiguity in perturbative QCD calculations. For dimensionless physical quantities we present a recipe for obtaining a RS invariant expansion (RSIE). An optimization procedure that leads to the RS invariant perturbation theory (RSIP...

| Summary: | We develop a formalism for resolving the renormalization scheme (RS) ambiguity in perturbative QCD calculations. For dimensionless physical quantities we present a recipe for obtaining a RS invariant expansion (RSIE). An optimization procedure that leads to the RS invariant perturbation theory (RSIPT), which yields finite-order predictions free from RS ambiguities, is suggested. |
