Equation of state at non-zero baryon density based on lattice QCD    [PDF]

Pasi Huovinen, Peter Petreczky, Christian Schmidt

We employ the lattice QCD data on Taylor expansion coefficients to extend our
previous 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. Parametrized lattice equation of state can thus be
smoothly connected to the hadron resonance gas equation of state at low
temperatures.
