One of the open questions in heavy-ion collisions is the mechanism of rapid thermalization. A general framework that does lead to thermalization is kinetic theory, so it is natural to ask how fast it would thermalize in QCD. Though 2->2 processes equilibrate too slowly, it has been argued based on calculations with the BAMPS transport model that 2<->3 processes, in particular ggg<->gg, quickly establish near hydrodynamic behavior. On the other hand, these results have since received some criticism, for example, that 2->3 cross sections in BAMPS may have been overestimated by as much as a factor of six. We revisit this question with our recently developed radiative transport code MPC/Grid.
