Abstract

We present results for the elliptic and triangular flow coefficients v₂ and v₃ in Au+Au collisions at √(s)=200 AGeV using event-by-event D=3+1 viscous hydrodynamic simulations. We study the effect of initial state fluctuations and finite viscosities on the flow coefficients v₂ and v₃ as functions of transverse momentum and pseudorapidity. Fluctuations are essential to reproduce the measured centrality dependence of elliptic flow. We argue that simultaneous measurements of v₂ and v₃ can determine \ensuremathη/s more precisely.
