Renormalization-scheme variation of a QCD perturbation expansion with tamed large-order behavior
Renormalization-scheme variation of a QCD perturbation expansion with tamed large-order behavior
The renormalization-scheme and scale dependence of the truncated QCD perturbative expansions is one of the main sources of theoretical error of the standard model predictions, especially at intermediate energies. Recently, a class of renormalization schemes, parametrized by a single real number $C$, has been defined and investigated in the frame …
