| Abstract |
The anisotropy parameter (ν2), the second harmonic of the azimuthal particle distribution, has been measured with the PHENIX detector in Au + Au collisions at √sNN p = 200 GeV for identified and inclusive charged particle production at central rapidities (|η| < 0.35) with respect to the reaction plane defined at high rapidities (|η| = 3–4 ). We observe that the ν2 of mesons falls below that of (anti)-baryons for pT > 2 GeV=c, in marked contrast to the predictions of a hydrodynamical model. A quark-coalescence model is also investigated.
