A ug 2 00 1 Hydrodynamical analysis of flow at RHIC

We use a hydrodynamical model to describe the evolution of th e collision system at collision energies √ s = 130 and 200 GeV. At lower √ s = 130 GeV energy we compare the results obtained assuming fast or slow thermalization (thermalization times τ0 = 0.6 and 4.1 fm/ c, respectively) and show that slow thermalization fails to reproduce the observed… CONTINUE READING
