3-to-3 Parton Elastic Scatterings and Early Thermalization

  • Triple-gluon elastic scatterings ggg→ggg and triple-quark elastic scatterings qqq→qqq are studied. The H-theorem extended to the transport equations with the 3→3 elastic scatterings is proved. A short thermalization time for gluon matter and a long thermalization time for quark matter are results of the transport equations.

Abstract: Triple-gluon elastic scatterings ggg→ggg and triple-quark elastic scatterings qqq→qqq are studied. The H-theorem extended to the transport equations with the 3→3 elastic scatterings is proved. A short thermalization time for gluon matter and a long thermalization time for quark matter are results of the transport equations.
