Abstract
We present high-precision measurements of elliptic, triangular, and quadrangular flow v2, v3, andv4, respectively, at midrapidity (|| < 1.0) for identified hadrons , p, K, , Ks, as a function ofcentrality and transverse momentum in Au+Au collisions at the center-of-mass energy sNN = 200GeV. We observe similar vn trends between light and strange mesons which indicates that the heavierstrange quarks flow as strongly as the lighter up and down quarks. The number-of-constituent-quarkscaling for v2, v3, and v4 is found to hold within statistical uncertainty for 0-10%, 10-40% and 40-80%collision centrality intervals. The results are compared to several viscous hydrodynamic calculationswith varying initial conditions, and could serve as an additional constraint to the development ofhydrodynamic models
