Abstract
The v2 and v4 of pions, kaons and protons have been measured by PHENIX in 200 GeV Au+Au collisions up to pT ~ 6 GeV/c and 4 GeV/c, respectively. The v4 of all these identified particles have been found to scale with the number of constituent quarks and all these particles have a similar v4/v22 ratio which is close to 0.9. The scaling behavior of v2 is studied at high pT and a deviation from the universal scaling is observed for transverse kinetic energy (KET/nq) higher than 1 GeV.
