Lattice QCD based equation of state at finite baryon density — •Pasi Huovinen — Frankfurt Institute for Advanced Studies (FIAS), Ruth-Moufang-Straße 1, D-60438 Frankfurt, Germany

We employ the lattice QCD data on Taylor expansion coefficients to extend the parametrization of the equation of state to finite baryon density. When we take into account lattice spacing and quark mass dependence of the hadron masses, the Taylor coefficients at low temperature are equal to those of hadron resonance gas. Thus we require that the equation of state is smoothly connected to the hadron resonance gas equation of state at low temperatures. We also show how the hydrodynamical evolution is affected by this equation of state in the energy range relevant for SPS and the RHIC energy scan.
