Description
Charged particles'pT spectra and elliptic flow in 0%-60% Au+Au collisions at the Relativistic Heavy Ion Collider are analyzed in a hydrodynamic model with hot hadronic resonance gas (HRG) in the initial state. Physically conceivable HRG, thermalized in the time scale τi=1 fm, at a (central) temperature Ti=220 MeV, with viscosity-to-entropy ratio η/s=0.24, explains the pT spectra in all the collision centralities reasonably well. However, centrality dependence of elliptic flow demands continual increase of the viscosity-to-entropy ratio with centrality.
