The phase diagram of QCD and its critical endpoint — •Franz Richard Sattler1, Jan Martin Pawlowski1,2, Friederike Ihssen1, and Nicolas Wink3 — 1Institut für Theoretische Physik, Philosophenweg 16, 69120 Heidelberg, Germany — 2ExtreMe Matter Institute EMMI, GSI, Planckstr. 1, 64291 Darmstadt, Germany — 3Institut für Kernphysik, Technische Universität Darmstadt, D-64289 Darmstadt, Germany
We investigate the location of the conjectured critical endpoint of QCD by using the functional renormalization group. This allows to access the high-density region, as this approach does not suffer from the sign problem of lattice QCD.
In this setup, we can systematically identify and include all relevant physical degrees of freedom.
We discuss both quantitative results in the vacuum as well as the extension to the phase diagram up to intermediate densities.
Finally, for calculations at even higher densities, we discuss future extensions of our setup, such as other potentially relevant composite particles.
