Abstract

Assuming that in Au+Au collisions, a baryon free fluid is produced, transverse momentum spectra of identified particles ( $π$ , $K$ , $p$ and $φ$ ), in evolution of ideal and viscous fluid is studied. Hydrodynamic evolution is governed by a lattice based equation of state (EOS), where the confinement-deconfinement transition is a cross-over at $T_{co}$

Assuming that in Au+Au collisions, a baryon free fluid is produced, transverse momentum spectra of identified particles (π, K, p and φ), in evolution of ideal and viscous fluid is studied. Hydrodynamic evolution is governed by a lattice based equation of state (EOS), where the confinement-deconfinement transition is a cross-over at T_co=196 MeV.
