Description

Heavy ion collisions at intermediate and high energies have been in recent years successfully modeled by hybrid approaches. These include viscous hydrodynamic evolution, particlization procedure and hadronic transport. The initial conditions for the hydrodynamic stage can be provided by a wealth of models. In this work we address the initialization from a transport model in the SMASH-vHLLE hybrid model framework, specifically the influence of different smearing kernels used to provide smooth initial conditions and the possibility to separate the incoming particles into softer hadrons that create the initial conditions and more energetic hadrons that provide further energy and momentum sources during the hydrodynamic evolution. Particularly flow observables are affected by these variations.
