Description

Recent years have brought interest in the baryon dense region of the QCD phase diagram, probed by low energy heavy ion collisions (HICs) performed by the STAR Beam Energy Scan at RHIC, and by the HADES/CBM experiments at the upcoming FAIR facility. Such HICs are correctly described by hybrid simulations of hadronic transport and viscous hydrodynamics, connected initially by the fluidization of hadrons. In low beam energy collisions, this process does not happen at the same time across the initial stage, but rather bubbles of fluid matter form and grow while absorbing more particles. Such expansion of the fluid depends on the input equation of state, in particular if a first-order phase transition is present. In this work, we present the new dynamic fluidization within the SMASH+vHLLE hybrid and the effect of different equations of state in low beam energy HICs.
