Abstract: (IOP)
The charged-particle final state spectrum is derived from an analytic perturbative solution for relativistic viscous hydrodynamics. By taking into account the longitudinal acceleration effect in relativistic viscous hydrodynamics, the pseudorapidity spectrum describes the nucleus-nucleus colliding systems at RHIC and the LHC well. Based on both the extracted longitudinal acceleration parameter and a phenomenological description of , the charged-particle pseudorapidity distributions for Xe+Xe collisions are computed from the final state expression in a limited space-time rapidity region.
