摘要

We present results for the elliptic and triangular flow coefficients v 2 and v3 in Au+Au collisions at √s=200AGeV 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 v 2 and v3 can determine η/s more precisely.
