Three-Fluid Simulations of Relativistic Heavy-Ion Collisions

Probing Equation of State (EoS) of QCD matter in relativistic heavy-ion collisions is still a fascinating problem inspiring new experimental projects [1]. Hydrodynamic models have an advantage that they directly address EoS of hot and dense nuclear matter, which is of prime interest for this domain of physics. We have developed 3D 3fluid relativistic hydrodynamic model [2, 3] for simulating heavy-ion collisions at incident energies from few to about 200 A·GeV. The model involves possibility to use various EoS including those with deconfinement phase transition of different orders.
