Pushing the hybrid approach to low beam energies with dynamic initial conditions from hadronic transport

This is the authors' abstract. We don't add key points for this paper.

While hybrid approaches of relativistic hydrodynamics + transport have been well established for the dynamical description of heavy-ion collisions at high beam energies, moving to lower beam energies is challenging. In this work, we propose dynamic initial conditions for the viscous hydrodynamic evolution in heavy-ion collisions at low to intermediate beam energies. They are comprised of core hadrons based on the local energy density during the preequilibrium hadronic evolution. The hybrid approach is then applied to lower beam energies, achieving good agreement with measured bulk observables between s N N = 3 and 9.1 GeV , thus providing theoretical guidance for the Beam Energy Scan performed by the STAR Collaboration at RHIC and the future Compressed Baryonic Matter experiment at GSI.
