The nu(2) and nu(4) of pions, kaons and protons have been measured by PHENIX in 200 GeV Au+Au collisions up to p(T) similar to 6 GeV/c and 4 GeV/c, respectively. The nu(4) of all these identified particles have been found to scale with the number of constituent quarks and all these particles have a similar nu(4)/nu(2)(2) ratio which is close to 0.9. The scaling behavior of nu(2) is studied at high p(T) and a deviation from the universal scaling is observed for transverse kinetic energy (KE(T)/n(q)) higher than 1 GeV.
