RS-Invariant All-Orders Renormalon Resummations for some QCD Observables


We propose a renormalon-inspired resummation of QCD perturbation theory based on approximating the renormalization scheme (RS) invariant effective charge beta-function coefficients by the portion containing the highest power of b=16(11N– 2Nf ), for SU(N) QCD with Nf quark flavours. This can be accomplished using exact large-Nf all-orders results. The… (More)
