Ideal hydrodynamics for bulk and multistrange hadrons in root s(NN)=200A GeV Au-Au collisions Academic Article

abstract

• We reexamine the use of ideal hydrodynamics to describe bulk- and multistrange-hadron observables in nuclear collisions at the Relativistic Heavy Ion Collider. Toward this end we augment the 2+1-dimensional code azhydro by employing (a) an equation of state based on recent lattice-QCD computations matched to a hadron-resonance gas with chemical decoupling at Tch 160 MeV, (b) a compact initial-density profile, (c) an initial-flow field including azimuthal anisotropies, and (d) a sequential kinetic decoupling of bulk (, K, p) and multistrange (, , ) hadrons at T110 and 160 MeV, respectively. We find that this scheme allows for a consistent description of the observed chemistry, transverse-momentum spectra, and elliptic flow of light and strange hadrons. 2012 American Physical Society.
