QCD at High Temperature : Results from Lattice Simulations with an Imaginary mu

Abstract

We summarize our results on the phase diagram of QCD with emphasis on the high temperature regime. For $T\ge 1.5T_c$ the results are compatible with a free field behavior, while for $T\simeq 1.1T_c$ this is not the case, clearly exposing the strongly interacting nature of QCD in this region
