Recent lattice QCD results, comparing to a hadron resonance gas model, have shown the need for hundreds of particles in hadronic models. These extra particles influence both the equation of state and hadronic interactions within hadron transport models. Here, we introduce the PDG21+ particle list, which contains the most up-to-date database of particles and their properties. We then convert all particles decays into 2 body decays so that they are compatible with SMASH in order to produce a more consistent description of a heavy-ion collision.more » « less

David, G. ; Garg, P. ; Kalweit, A. ; Mukherjee, S. ; Ullrich, T. ; Xu, Z. ; Yoo, I.-K. (Ed.)We use the excluded volume Hadron Resonance Gas (HRG) model with the most up-to-date hadron list to calculate η T/w at low temperatures and at finite baryon densities ρ B . This η T/w is then matched to a QCD-based shear viscosity calculation of the QGP for different profiles of η T/w across T,μ B including cross-over and critical point transitions. When compared to ideal hydrodynamic trajectories across T,μ B , we find that the η T/w (T,μ B ) profiles would require initial conditions at much larger baryon density to reach the same freeze-out point.more » « less
