Transport and spectral functions in high-temperature QCD

Presenter: Gert Aarts — Swansea University

Due to the progress in relativistic heavy ion collisions, transport properties of the quark gluon plasma are currently of great interest. The success of ideal hydrodynamics in heavy ion phenomenology has led to the `perfect fluid' paradigm of the strongly coupled QGP (sQGP). In lattice QCD, transport coefficients and spectral functions can be extracted from euclidean correlators obtained in numerical simulations using the Maximum Entropy Method. I review recent developments and discuss first results for transport coefficients in quenched QCD.
