Strangeness-neutral equation of state for QCD with a critical point.

ORAL

Abstract

We construct a family of equations of state for QCD in the temperature range 30$\le $T$\le $800 MeV and in the chemical potential range 0$\le \mu $B$\le $450 MeV [1]. These equations of state match available lattice QCD results up to O($\mu $B\textasciicircum 4) and in each of them we place a critical point in the 3D Ising model universality class. Our results for the pressure, entropy density, baryon density, energy density and speed of sound can be used as inputs in the hydrodynamical simulations of the fireball created in heavy ion collisions. We follow the approach presented in Ref. [2], but we extend it to a more realistic scenario, which reflects the net-strangeness and net-electric charge content of the colliding nuclei in heavy-ion collisions. [1] J. M. Karthein, D.
