scattering in the -meson channel at finite temperature
Y. B. He, J. Hüfner, S. P. Klevansky +1
We study scattering in the I=1, channel at finite temperature in the framework of the extended Nambu-Jona-Lasinio model that explicitly includes vector and axial-vec…
Derivation of transport equations for a strongly interacting Lagrangian in powers of and
S. P. Klevansky, A. Ogura, J. Hüfner
Transport theory for an interacting fermionic system is reviewed and applied to the chiral Lagrangian of the Nambu-Jona-Lasinio model. Two expansions must be applied: an expansion…
Spectral Density Functions and Their Sum Rules in an Effective Chiral Field Theory
S. P. Klevansky, R. H. Lemmer
The validity of Weinberg's two sum rules for massless QCD, as well as the six additional sum rules introduced into chiral perturbation theory by Gasser and Leutwyler, are investiga…
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…
Confinement in the Coulomb Gauge Model
Th. Wilke, S. P. Klevansky
The Coulomb gauge model of QCD is studied with the introduction of a confining potential into the scalar part of the vector potential. Using a Green function formalism, we derive t…
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…
