# Improved cooling algorithm for gauge theories

## TL;DR

This paper introduces a new 'gold-washing' algorithm for gauge theories that effectively smooths short-range fluctuations while preserving larger instantons, requiring no monitoring or calibration.

## Contribution

The paper presents a novel, calibration-free smoothing algorithm that selectively preserves instantons above a certain size in gauge theories.

## Key findings

- Effective smoothing of short-range fluctuations.
- Preserves instantons above a certain size.
- No monitoring or calibration needed.

## Abstract

We propose and study a ``gold-washing" - type of algorithm which smooths out the short range fluctuations but leaves invariant instantons above a certain size. The algorithm needs no monitoring or calibration.
