Bulk Properties of the Matter Produced at Energies of the Beam Energy Scan Program

Understand

Recent STAR data on the bulk observables in the energy range of the Beam-Energy Scan Program at the Relativistic Heavy-Ion Collider are analyzed within the model of the three-fluid dynamics (3FD).

• The simulations are performed with different equations of state (EoS).
• The purely hadronic EoS fails to reproduce the data.
• A good, though imperfect, overall reproduction of the data is found within the deconfinement scenarios.
