The QCD phase diagram from lattice simulations — •Owe Philipsen — Institut für Theoretische Physik, Universität Münster, Germany

The QCD phase diagram tells us the different forms in which nuclear matter exists as a function of temperature and baryon chemical potential, as well as the location of phase transitions between them. Because of the so-called sign problem of lattice QCD, first principles calculations at finite baryon chemical potential are impossible and simulations have to use detours which are valid for small densities only. I review recent simulation results. Because of strong discretization effects, it is not yet possible to draw conclusions for the continuum phase diagram.
