Abstract

The authors of [Phys. Rev. D 94, 014502 (2016)] reported about a careful analysis of the impact of lattice artifacts on the SU(3) gauge-field propagators. In particular, they found that the low-momentum behavior of the renormalized propagators depends on the lattice bare coupling and interpreted this as the result of its being affected by discretization artifacts. We discuss here a different interpretation for these results.
