Description
We study thermalization of gluons with momentum $p$ characterized by $Q$ in spatially homomgeneous systems. In initially under-populated systems in which the equilibrium temperature $T\ll Q$, soft gluons are found to be rapidly generated via radiation to fill a classical thermal distribution $\propto T^*/p$ with $T^*\gg T$. Thermal equilibrium is established only after $T^*$ approaches to $T$ via radiation. Similar features are also found among soft gluons in initially over-populated cases. In these cases, thermal equilibrium is established when the momentum of gluons increases from $Q$ to $T$ mainly due to momentum broadening. No transient formation of the Bose-Einstein condensate is observed.
