Hybrid approach to relativistic heavy-ion collisions at the RHIC BES energies

Using a hybrid (hydrodynamics + hadronic cascade) framework, we model the bulk dynamics of relativistic heavy-ion collisions at the RHIC BES collision energies, including the effects from non-zero net baryon current and its dissipative diffusion during the evolution. The framework is in full 3+1 dimension which allows us to study the non-trivial longitudinal structure and dynamics of the collision systems, for example, the baryon stopping. The collision energy dependence of hadronic chemistry, identified particle spectra, and anisotropic flows are studied at 19.6 GeV. Effects of breaking boost-invariance, net-baryon current, and its related diffusion on hadronic observables will be addressed.
