# QCD at high density: Equation of state for nuclear collisions and neutron stars

@article{Motornenko2019QCDAH, title={QCD at high density: Equation of state for nuclear collisions and neutron stars}, author={Anton Motornenko and Volodymyr Vovchenko and Jan Steinheimer and Stefan Schramm and Horst Stoecker}, journal={Nuclear Physics A}, year={2019} }

Abstract A unified chiral mean field approach is presented for QCD thermodynamics in a wide range of temperatures and densities. The model simultaneously gives a satisfactory description of lattice QCD thermodynamics and fulfills nuclear matter and astrophysical constraints. The resulting equation of state can be incorporated in relativistic fluid-dynamical simulations of heavy-ion collisions and neutron stars mergers. Access to different regions of the QCD phase diagram can be obtained in…
