Collision integral in a model for scalar quarks and gluons
D. S. Isert, S. P. Klevansky
A model of scalar quarks and scalar gluons is used to derive transport equations for quarks and gluons. In particular, the collision integral is studied. The self-energy diagrams a…
Classification of higher order diagrams in non-equilibrium theory, and the removal of pinch singularities
D. S. Isert, S. P. Klevansky
The non-equilibrium two loop self-energy is reexamined in the framework of a scalar quark and gluon model, with specific attention to terms which do not give rise to the standard t…
Collision integral for multigluon production in a scalar quark and gluon model
D. S. Isert, S. P. Klevansky
A model of scalar gluons and scalar quarks that successfully gives a ln s behavior in high energy qq scattering and which contains a three gluon vertex is used to derive transport…
Developing Transport Theory to Study the Chiral Phase Transition
S. P. Klevansky, A. Ogura, P. Rehberg +1
Chiral symmetry is an important aspect of QCD. Modelling this via the Nambu-Jona-Lasinio model, we construct a complete relativistic transport theory for quarks and mesons. The col…
Developing Transport Theory to Systematically Include Mesons And Hadronization
S. P. Klevansky, P. Rehberg, A. Ogura +1
Transport theory for the Nambu--Jona-Lasinio (NJL) model is examined. The collision term is investigated in a first approach in a coupling strength expansion. It can be demonstrate…
