Shear Viscosity from the Nambu–Jona-Lasinio Model — •Robert Lang, Norbert Kaiser, and Wolfram Weise — Physik Department, Technische Universität München, D-85747 Garching, Germany
The Nambu–Jona-Lasinio (NJL) model provides a good description of strongly-interacting matter where confinement does not play the major role. In the vicinity of the chiral cross over we apply this model to calculate the T and µ dependence of the shear viscosity η. The theoretical foundations are a systematic large-Nc analysis of the NJL model and the Kubo formalism for the calculation of transport coefficients.
