abstract
We study the QCD phase diagram by first principle lattice calculations at so far unreached high densities. For this purpose we employ the density of states method. Unimproved staggered fermions, which describe four quark flavors in the continuum are used in this analysis. Though the method is quite expensive, small lattices show an indication for a triple-point connecting three different phases on the phase diagram.

Lattice QCD constraints on the critical point from an improved precision equation of state
An improved lattice QCD equation of state, combined with entropy contours continued from imaginary chemical potential, excludes a QCD critical point below μB = 450 MeV at 2σ confidence.
