Application of the Hydrodynamic Event Generator THESEUS to CBM — •Elena Volkova for the CBM collaboration — The University of Tübingen, Tübingen, Germany

The Compressed Baryonic Matter experiment (CBM) at FAIR will measure nucleus-nucleus collisions at beam energies up to 14AGeV. The key objective of CBM is to investigate the QCD phase diagram in the region of the highest net-baryon-densities. The experiment is well suited to explore the Equation-of-State of nuclear matter at densities as they might occur in the interior of neutron stars or during neutron star mergers.

Recently, a new event generator (P. Batyuk et al. "Three-fluid Hydrodynamics-based Event Simulator Extended by UrQMD final State interactions (THESEUS) for FAIR-NICA-SPS-BES/RHIC energies") based on the three-fluid hydrodynamics approach for the early stage of the collision, followed by a particlization at the hydrodynamic decoupling surface to join to a microscopic transport model, UrQMD, to account for hadronic final state interactions has been developed. The generator allows, e.g., to employ different Equations-of-State for the description of nuclear matter.

In this poster, we present first results obtained with this new Event Generator apply it to the description of heavy-ion collisions in the CBM experiment.
