Abstract

The FASTSUM collaboration presents a study on the temperature dependence of the electrical conductivity o in the quark-gluon plasma, using the methods of lattice QCD. Correlators of the exactly conserved vector current are measured at different temperatures across the deconfinement transition, using ensembles of 2+1 flavours of dynamical fermions on anisotropic lattices. We then employ bayesian methods (MEM) to extract the relevant spectral functions, which are found to be consistent with o=T rising as a function of T. The robustness of the results is verified by a detailed analysis of the systematics involved in the bayesian reconstruction of the spectral functions.
