Pair production in strong SU (2) background fields

摘要

Fermion particle pair production in strong SU (2)-gauge chromoelectric fields is studied using the Boltzmann-Vlasov equation in a classical way. The existence of a preproduction process in a classical description is shown using the distribution evolution of non-Abelian particle production. It is interesting to find that the distribution of the particle number density is centered on two islands and shows a split on the color charge sphere as it evolves, ultimately reaching a steady state that is related to the amplitude and variation of the field.
