Transasymptotics and hydrodynamization of the Fokker-Planck equation for gluons

Understand

We investigate the non-linear transport processes and hydrodynamization of a system of gluons undergoing longitudinal boost-invariant expansion.

• The dynamics is described within the framework of the Boltzmann equation in the small-angle approximation.
• The kinetic equations for a suitable set of moments of the one-particle distribution function are derived.
• By investigating the stability and asymptotic resurgent properties of this dynamical system, we demonstrate, that its solutions exhibit a rather different behavior for large (UV) and small (IR) effective Knudsen numbers.
