Abstract
The azimuthal anisotropy parameter v2 has been measured with high statistics for identified hadrons in Au+Au collisions with the STAR experiment. At high transverse momentum (pT) a strong v2 for π++π− and is observed. In the intermediate pT region, number-of-constituent-quark scaling was tested to high precision. A detailed comparison of v2 for the multi-strange hadrons ϕ, , and with other particle species substantiates the development of collectivity among partons in the early phase of the collisions at RHIC.
