# Comment on "Lattice Gluon and Ghost Propagators, and the Strong Coupling in Pure $SU(3)$ Yang-Mills Theory: Finite Lattice Spacing and Volume Effects"

## TL;DR

This paper critiques a previous analysis of lattice artifacts in $SU(3)$ Yang-Mills theory, offering an alternative explanation for the observed low-momentum behavior of gauge-field propagators.

## Contribution

It provides a new interpretation of lattice artifact effects on propagators, challenging prior conclusions about their dependence on the bare coupling.

## Key findings

- Proposes an alternative explanation for low-momentum propagator behavior.
- Challenges the interpretation that finite lattice spacing artifacts depend on the bare coupling.
- Suggests that the observed effects are due to different factors than previously thought.

## Abstract

The authors of ref. Phys.Rev. D94 (2016) no.1, 014502 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 fact as the result of it being affected by finite lattice spacing artifacts. We do not share this interpretation and present here a different and more suitable explanation for these results.
