Query: Early thermalization of quark-gluon matter with the elastic scattering
  of ggq and ggqbar   Elastic gluon-gluon-quark (gluon-gluon-antiquark) scattering is studied in
perturbative QCD with 123 Feynman diagrams at the tree level. Individually
squared amplitudes and interference terms of the Feynman diagrams are derived.
With the elastic gluon-gluon-quark scattering and the elastic
gluon-gluon-antiquark scattering transport equations are established. In the
thermalization process of initially created quark-gluon matter, this matter is
governed by elastic 2-to-2 scattering and elastic 3-to-3 scattering. Solutions
of the transport equations show that initially created quark-gluon matter takes
early thermalization, i.e., thermal states are established rapidly. Different
thermalization times of gluon matter and quark matter are obtained.
