Triple-Gluon and Triple-Quark Elastic Scatterings and Early Thermalization

Abstract

Three-gluon to three-gluon scatterings lead to rapid thermalization of gluon matter created in central Au-Au collisions at RHIC energies. Thermalization of quark matter is studied from three-quark to three-quark scatterings.Comment: 8 pages, 5 figures, talk presented at the workshop on quark-gluon-plasma thermalization, TU Wien, Vienna, Austria, Aug. 2005. v2: add two figures and relevant discussion
