Description
Heavy-ion collisions provide a unique opportunity to study the phase structure of the QCD matter in the laboratory for a wide range of densities and temperatures. Dynamical models are required to extract information about the properties of QCD matter, such as the equation of state. I first present recent dynamical models which simulate heavy-ion collisions in the regime of high baryon densities. A dynamical coupling of the microscopic transport model and macroscopic hydrodynamics is implemented in the JAM code. It uses the dynamical initialization of fluid and solves the time evolution of a particle-fluid system. Next, I present the beam energy dependence of directed flow (v1) of protons from the microscopic transport approach of relativistic quantum molecular dynamics. I discuss the dynamical origin of sign change of proton v1 at 11.5GeV discovered by STAR-BES experiment.
