Abstract

We report the measurement of anisotropic flow at RHIC - PHENIX experiment. We present the v₄ results at sqrt(s_NN) = 200 GeV in Au+Au collision. The scaling ratio of v₄/(v₂)² is about 1.5 and it is found to be smaller than the prediction from simple coalescence model. The v₂ for high p_T identified particles (∼ 5 GeV/c) measured with Aerogel Cherenkov Counter are presented. We discuss the constituent quark scaling of v₂ for identified particles. We also report the first observation of v₂ for inclusive charged hadrons as well as identified hadrons at sqrt(s_NN) = 200 GeV in Cu+Cu collisions. The system size dependence of v₂ and scaling properties are discussed.
