Spectral Functions and Transport in High Temperature QCD

Abstract

The relativistic heavy ion experiments at RHIC have made it clear that is important to understand real-time and nonequilibrium processes in the quark-gluon plasma. In this talk I focus on two developments, connected through the construction of spectral functions from lattice QCD correlators: charmonium in lattice QCD with two dynamical fermion flavours at high temperature and transport coefficients and spectral functions at small energies obtained via the Maximum Entropy Method. For more details and much more references I refer to a recent review.1)
