# Topology by improved cooling: susceptibility and size distributions

## TL;DR

This paper introduces an improved cooling algorithm for SU(2) Yang-Mills theory that efficiently measures instanton susceptibility and size distributions without calibration, enhancing the analysis of topological structures.

## Contribution

The authors develop a scale-invariant cooling method that automatically suppresses dislocations, providing more accurate topological measurements in lattice gauge theory.

## Key findings

- Accurate susceptibility data for SU(2) Yang-Mills theory
- Reliable size distributions of instantons
- No need for monitoring or calibration in the cooling process

## Abstract

We use a cooling algorithm based on an improved action with scale invariant instanton solutions, which needs no monitoring or calibration and has a inherent cut off for dislocations. We present results for SU(2) Yang-Mills theory where the method provides good susceptibility data and physical size distributions of instantons.
