# Gauge--invariant field correlators in QCD at finite temperature

## TL;DR

This paper investigates how gauge-invariant two-point correlation functions of gauge fields behave across the deconfinement transition in QCD using lattice simulations.

## Contribution

It provides new numerical data on gauge-invariant correlators in QCD at finite temperature, focusing on the deconfinement phase transition.

## Key findings

- Correlation functions change significantly across the transition
- Results support models of deconfinement involving gauge field correlations
- Provides benchmarks for theoretical models of QCD at finite temperature

## Abstract

We study by numerical simulations on a lattice the behaviour of the gauge--invariant two--point correlation functions of the gauge field strengths across the deconfinement phase transition.
