Isentropic Equation of State of Two-Flavour QCD in a Quasi-Particle Model

Bluhm, M.; Kämpfer, B.; Schulze, R.; Seipt, D.

We examine the isentropic QCD equation of state within a quasi-particle model being adjusted to first principle QCD calculations of two quark flavours. In particular, we compare with Taylor expansion coefficients of energy and entropy densities and with the isentropic trajectories describing the hydrodynamical expansion of a heavy-ion collision fireball.

Keywords: QCD Equation of State; Quasi-particle model
