Renormalization-Scheme Dependence of Padé Summation in QCD
We study the renormalization-scheme (RS) dependence of Padé Approximants (PA's), and compare them with the Principle of Minimal Sensitivity (PMS) and the Effective Charge (ECH) approaches. Although the formulae provided by the PA, PMS and ECH predictions for higher-order terms in a QCD perturba...
