TL;DR
This paper studies how the Yang-Mills-Higgs system reaches thermal equilibrium at high temperatures by analyzing the Lyapunov exponents and their relation to damping rates of gauge bosons.
Contribution
It provides a detailed analysis of thermalization time scales and establishes a connection between Lyapunov exponents and gauge boson damping rates in the Yang-Mills-Higgs theory.
Findings
Largest Lyapunov exponent correlates with damping rate
Thermalization occurs at multiple time scales
Relation between chaos indicators and perturbative calculations
Abstract
We investigate thermalization processes occurring at different time scales in the Yang-Mills-Higgs system at high temperatures. We determine the largest Lyapunov exponent associated with the gauge fields and verify its relation to the perturbatively calculated damping rate of a static gauge boson.
