Pair production in strong SU(2) background fields

TL;DR

This paper investigates fermion pair production in strong SU(2) chromoelectric fields using a classical Boltzmann-Vlasov approach, revealing a pre-production process and a unique distribution pattern related to field dynamics.

Contribution

It demonstrates the classical pre-production process of non-Abelian pair creation and characterizes the evolving distribution of particles in color charge space.

Findings

Distribution centers form two islands with a split on the color charge sphere.

Particle distribution reaches a steady state influenced by field amplitude and variation.

Classical description captures key features of non-Abelian pair production.

Abstract

The fermion particle pair production in strong SU(2) gauged chromoelectric fields is studied by using Boltzmann-Vlasov equation in a classical way. The existence of pre-production process in a classical description is shown with the distribution evolution of non-Abelian particle production. It is interesting to find that the distribution center of particle number density is on two islands and has a split on color charge sphere as it evolutes and reaches a steady state at last, which is related to the amplitude and the varying of the field.
