Anisotropic flow in event-by-event ideal hydrodynamic simulations of √[s(NN)]=200 GeV Au+Au collisions.

We simulate top-energy Au+Au collisions using ideal hydrodynamics in order to make the first comparison to the complete set of midrapidity flow measurements made by the PHENIX Collaboration. A simultaneous calculation of v(2), v(3), v(4), and the first event-by-event calculation of quadrangular flow defined with respect to the v(2) event plane (v(4){Ψ(2)}) gives good agreement with measured values, including the dependence on both transverse momentum and centrality. This provides confirmation that the collision system is indeed well described as a quark-gluon plasma with an extremely small viscosity and that correlations are dominantly generated from collective effects. In addition, we present a prediction for v(5).
