AB The SUð3Þ gauge-field propagators computed from the lattice have been exhaustively used in theinvestigation of the low-momentum dynamics of QCD, in a judicious interplay with results from othernonperturbative approaches, and for the extraction of fundamental parameters of QCD like ΛMS as well.The impact of the discretization artifacts and their role in the extrapolation of the results to the continuumlimit have not been fully understood so far. We report here about a very careful analysis of the physicalscaling violation of the Landau-gauge propagators renormalized in the momentum subtraction scheme andthe Taylor coupling, steering us towards an insightful understanding of the effects from discretizationartifacts which makes therefore possible a reliable continuum-limit extrapolation.
