The role of the gluonic gg <-> ggg interactions in early thermalization in a ultrarelativistic heavy-ion collision

Zhe Xu

We report the status of the present investigations of partonic dynamics in ultrarelativistic heavy-ion reactions using a microscopical 3+1 dimensional parton cascade including gluonic inelastic gg <-> ggg scatterings. The major emphasis is put on the understanding of the dominant role of gg <-> ggg scatterings in thermalization and its dependence on the choosen initial conditions of partons.
