Hydrodynamical analysis of flow at RHIC
P. Huovinen
Abstract
We use a hydrodynamical model to describe the evolution of the collision system at collision energies sqrts=130 and 200 GeV. At lower sqrts=130 GeV energy we compare the results obtained assuming fast or slow thermalization (thermalization times tau0=0.6 and 4.1 fm/c, respectively) and show that slow thermalization fails to reproduce the observed anisotropy of particle distribution. At sqrts=200 GeV collision energy our results show anisotropies similar to those observed at sqrts=130 GeV.
