Comment on ``Evidence Against Instanton Dominance of Topological Charge Fluctuations in QCD''

TL;DR

This paper challenges a recent claim by providing calculations with an overlap action that support instanton dominance in the topological charge fluctuations of QCD.

Contribution

It offers new computational evidence using an overlap action to support instanton dominance, countering previous conclusions.

Findings

Supports instanton dominance in QCD topological fluctuations

Uses overlap action for fermionic eigenmodes analysis

Contradicts recent claims against instanton dominance

Abstract

We comment on the recent paper (hep-lat/0102003) by Horvath, Isgur, McCune, and Thacker, which concludes that the local chiral structure of fermionic eigenmodes is not consistent with instanton dominance. Our calculations, done with an overlap action, suggest the opposite conclusion.
