A high-statistics sample of gauge configurations used to evaluate the coupling from ghost and gluon propagators allows for the appropriate update of previous results, now performing an improved analysis of data with reduced statistical errors and the systematical uncertainties under a better control.application/pdfenAmerican Physical SocietyLatticeTaylor schemejournal articleopen access
