Real--time dynamics of a hot Yang-Mills theory: a numerical analysis

TL;DR

This paper presents numerical simulations of high-temperature SU(2) Yang-Mills theory, analyzing real-time dynamics and autocorrelations, and concludes that the ASY-Bodecker scenario does not apply at electroweak-scale temperatures.

Contribution

It provides new numerical insights into the real-time behavior of hot Yang-Mills theory, challenging the relevance of the ASY-Bodecker scenario at these energies.

Findings

ASY-Bodecker scenario is irrelevant at electroweak temperatures

Autocorrelation measurements inform about gauge field dynamics

Numerical methods applied to classical Yang-Mills simulations

Abstract

We discuss recent results obtained from simulations of high temperature, classical, real time dynamics of SU(2) Yang-Mills theory at temperatures of the order of the electroweak scale. Measurements of gauge covariant and gauge invariant autocorrelations of the fields indicate that the ASY-Bodecker scenario is irrelevant at these temperatures.
