dc.description.abstractUsing the UrQMD/coarse graining approach we explore the kinetic freeze-out stage in central Au + Au collisions at various energies. These studies allow us to obtain detailed information on the thermodynamic properties (e.g. temperature and chemical potential) of the system during the kinetic decoupling stage. We explore five relevant collision energies in detail, ranging from √sNN=2.4 GeV (GSI-SIS) to √sNN=200 GeV (RHIC). By adopting a standard Hadron Resonance Gas equation of state, we determine the average temperature〈T〉and the average baryon chemical potential〈μB〉on the space-time hyper-surface of last interaction. The results highlight the nature of the kinetic freeze-out as a continuous process. This differential decoupling is an important aspect often missed when summarizing data as single points in the phase diagram as e.g. done in Blast-Wave fits. We compare the key properties of the system derived by using our approach with other models and we briefly review similarities and differences.en
