The QCD phase diagram and the critical point (A01)

• Subject Area: Nuclear and Elementary Particle Physics, Quantum Mechanics, Relativity, Fields
• Term: from 2008 to 2020
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 35592816

We analyze the equation of state and various fluctuations of conserved charges by analytic continuation to imaginary chemical potential. We plan to determine the nature of the transition at the Roberge-Weiss point. We will explore the phase diagram using the reweighting technique to locate or rule out the existence of the critical end point in the baryonic chemical potential range of 0-200 MeV. We want to study the Columbia plot at zero chemical potential. For this, we plan to use overlap fermions.
