This review examines the transport properties of strongly interacting quark-gluon plasma in heavy-ion collisions, comparing out-of equilibrium and equilibrium states. By studying transport coefficients in relation to temperature and baryon chemical potential, the authors discuss observables sensitive to the formation and properties of the QGP.
We review the transport properties of the strongly interacting quark-gluon plasma (QGP) created in heavy-ion collisions at ultrarelativistic energies, i.e. out-of equilibrium, and compare them to the equilibrium properties. The description of the strongly interacting (non-perturbative) QGP in equilibrium is based on the effective propagators and couplings from the Dynamical QuasiParticle Model (DQPM) that is matched to reproduce the equation-of-state of the partonic system above the deconfinement temperature T ( c ) from lattice QCD. We study the transport coefficients such as the ratio of shear viscosity and bulk viscosity over entropy density, diffusion coefficients, electric conductivity etc versus temperature T and baryon chemical potential mu ( B ). Based on a microscopic transport description of heavy-ion collisions we, furthermore, discuss which observables are sensitive to the QGP formation and its properties.
