Description

We study the transport properties of strongly interacting matter in the vicinity of the phase transition for different effective models, i.e. the Nambu-Jona-Lasinio (NJL) model and the Dyniamical QuasiParticle Model (DQPM) for 3 quark flavours. We present our results on the temperature dependence of the shear and bulk viscosity (calculated within the relaxation time formalism), as well as of the electric and heat conductivity in comparison to recent lattice data [1]. These transport coefficients allow for discussing quantitatively how fast particles traverse the quark gluon plasma and open the possibility to compare different approaches for the expansion of the quark gluon plasma created in ultrarelativistic heavy-ion collisions. The comparison of the final observables (multiplicity, v_2, v_3, \dots) for realistic simulations based on these models are presented within the Parton-Hadron-String Dynamics (PHSD) and the Relativistic quantum molecular dynamics for Strongly interacting matter with Phase transition or crossover (RSP) [2].
