abstract = {The SUð3Þ gauge-field propagators computed from the lattice have been exhaustively used in the
investigation of the low-momentum dynamics of QCD, in a judicious interplay with results from other
nonperturbative 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 continuum
limit have not been fully understood so far. We report here about a very careful analysis of the physical
scaling violation of the Landau-gauge propagators renormalized in the momentum subtraction scheme and
the Taylor coupling, steering us towards an insightful understanding of the effects from discretization
artifacts which makes therefore possible a reliable continuum-limit extrapolation.},
