Description

In hydrodynamical modeling of heavy-ion collisions, the equation of state (EoS) is usually taken to be lattice QCD EoS. However, the still often used parametrisation for lattice QCD EoS, s95p, is strictly speaking not compatible with the contemporary lattice QCD results. We have devised a new family of EoS parametrisations based on hotQCD and Budapest-Wuppertal data, and different lists of resonances in the hadronic phase, and carry out Bayesian analysis to find out whether these different EoSs will lead to different favoured values of eta/s.
