| Abstract: | Flow coefficients v_n for n = 2, 3, 4, characterizing the anisotropic
collective flow in Au+Au collisions at sqrt(s_NN) = 200 GeV, are measured
relative to event planes Psi_n determined at large rapidity. We report v_n as
a function of transverse momentum and collision centrality, and study the
correlations among the event planes of different order n. The v_n are well
described by hydrodynamic models which employ a Glauber Monte Carlo initial
state geometry with fluctuations, providing additional constraining power on
the interplay between initial conditions and the effects of viscosity as the
system evolves. This new constraint improves precision of the extracted
viscosity to entropy density ratio eta/s. |
