Anisotropic flow in heavy-ion collisions at high and low beam energies — •Hannah Elfner — GSI, Darmstadt, Germany — Goethe University, Frankfurt, Germany — FIAS, Frankfurt, Germany

The collective behavior of particles emitted from heavy-ion collisions is sensitive to the properties of the hot and dense medium that is produced. At high beam energies as they are studied at LHC or RHIC detailed measurements of higher order flow coefficients and their correlations are available. Comparing the experimental data for bulk observables with sophisticated dynamical hybrid approaches based on viscous hydrodynamics and hadronic transport allows conclusions about the transport coefficients of QCD matter and their temperature dependence. At lower beam energies as they are reached at GSI and in the future at FAIR the high density regime of QCD is explored. The collective flow measurements are sensitive to the equation of state of nuclear matter and recent progress concerning transport calculations with mean fields will be explained. In both cases, Bayesian multi-parameter analysis are employed to obtain results with quantified uncertainties.
