摘要：
Event anisotropy is expected to have sensitivity to the early stage of ultra-relativistic heavy-ion collisions at RHIC. The possible formation of a quark gluon plasma (QGP) could affect how the initial anisotropy in the space coordinate is transferred into the momentum space for the final state. The anisotropy parameter (v(2)) is an amplitude of the 2nd harmonic parameter of the azimuthal distribution with respect to the reaction plane. We present here v(2) of identified (pi(+), pi(-), K+, K-, p and p) and inclusive charged particles measured in the PHENIX central arm detector (\eta\ < 0.35) with respect to the reaction plane defined at \eta\ = 3 similar to 4 in 200 GeV Au+Au collisions.
