Transport coefficients in a generalized quasiparticle model — •Thorsten Steinert — Institut für Theoretische Physik, JLU Giessen, 35392 Giessen, Germany

The QCD equation of state as predicted by lattice QCD calculations (lQCD) is well reproduced in terms of effective quasiparticle models. We present a generalised quasiparticle model where the partonic propagators explicitly depend on the three-momentum with respect to the medium. Within this extended model we reproduce simultaneously the equation of state and the susceptibilties as provided by lQCD. We calculate the shear and bulk viscosity as well as the electric conductivity and compared them to default quasiparticle models and available lattice data. We discuss the behavior of the transport coefficients as a function of finite chemical potential.
