The Principle of Maximum Conformality
Brodsky, Stanley.
The Principle of Maximum Conformality provides a consistent method for determining the renormal-
ization scale in pQCD. The PMC scale-fixed prediction is independent of the choice of
renormalization scheme, a key requirement of renormalization group invariance. The results
avoid renormalon resummation and agree with QED scale-setting in the Abelian limit. The
PMC global scale can be derived effciently at NLO from basic properties of the PQCD cross
section. The elimination of the renormalization ... Show Full Abstract
The Principle of Maximum Conformality provides a consistent method for determining the renormal-
ization scale in pQCD. The PMC scale-fixed prediction is independent of the choice of
renormalization scheme, a key requirement of renormalization group invariance. The results
avoid renormalon resummation and agree with QED scale-setting in the Abelian limit. The
PMC global scale can be derived effciently at NLO from basic properties of the PQCD cross
section. The elimination of the renormalization scheme ambiguity using the PMC will not
only increases the precision of QCD tests, but it will also increase the sensitivity of colliders
to new physics beyond the Standard Model.
