QCD topology using scale controlled cooling: Densities and cooling invariant observables

TL;DR

This paper introduces a scale-controlled smoothing method to analyze QCD topology, focusing on invariant observables that reduce uncertainties in instanton ensemble characterization.

Contribution

It presents a novel scale-controlled cooling technique and identifies observables that are independent of microscopic instanton details.

Findings

Reduced uncertainties in topological structure analysis

Development of scale-invariant observables

Enhanced robustness of instanton ensemble characterization

Abstract

We aim at reducing the uncertainties inherent in the analysis of the topological structure by using scale controlled smoothing and observables independent on the "microscopic" description of the instanton ensemble.
