Subject: The QCD phase transition and its signatures in heavy-ion collisions

For a complete understanding of the QCD phase diagram it is important to connect first-principle thermodynamic calculations to experimental data from heavy-ion collision experiments of the RHIC Beam Energy Scan. In particular, the potential to discover the QCD critical point experimentally is of great interest. In this talk I will review the theoretical concepts of critical fluctuations at the QCD phase transition and discuss the current status of modeling these fluctuations in the dynamical evolution of heavy-ion collisions. Within the model of nonequilibrium chiral fluid dynamics I will show how different equations of state at finite baryochemical affect the dynamical domain formation at a first-order phase transition. Special emphasis is put on observables which are sensitive to the critical point and how they are affected by the out-of-equilibrium dynamics in heavy-ion collisions.
