A key issue in making precise predictions in QCD is the uncertainty in setting the
renormalization scale μ r and thus determining the correct values of the QCD running …

The conventional scale setting approach to fixed-order perturbative QCD (pQCD)
predictions is based on a guessed renormalization scale, usually taking as the one to …

A valid prediction for a physical observable from quantum field theory should be
independent of the choice of renormalization scheme—this is the primary requirement of …

In addition to the evaluation of high-order loop contributions, the precision and predictive
power of perturbative QCD (pQCD) predictions depends on two important issues:(1) how to …

The intrinsic conformality (iCF) is a general property of the renormalizable gauge theory,
which ensures the scale invariance of a fixed-order series at each perturbative order …

The principle of maximal conformality (PMC) provides a rigorous method for eliminating
renormalization scheme-and-scale ambiguities for perturbative QCD (pQCD) predictions …

As a basic requirement of the renormalization group invariance, any physical observable
must be independent of the choice of both the renormalization scheme and the initial …

The quantum chromodynamics (QCD) coupling α s is the most important parameter for
achieving precise QCD predictions. By using the well measured effective coupling ${\alpha} …

A bstract We present a novel method for precisely determining the QCD running coupling
from R uds measurements in electron-positron annihilation. When calculating the fixed-order …

The predictive power of perturbative QCD (pQCD) depends on two important issues:(1) how
to eliminate the renormalization scheme-and-scale ambiguities at fixed order, and (2) how to …
