Abstract
Measurements of the anisotropy parameter v 2 of identified hadrons (pions, kaons, and protons) as a function of centrality, transverse momentum p T, and transverse kinetic energy KE T at midrapidity (

η

<0.35) in Au+Au collisions at √s NN=200 GeV are presented. Pions and protons are identified up to p T= 6 GeV/c, and kaons up to p T= 4 GeV/c, by combining information from time-of-flight and aerogel Čerenkov detectors in the PHENIX Experiment. The scaling of v 2 with the number of valence quarks (n q) has been studied in different centrality bins as a function of transverse momentum and transverse kinetic energy. A deviation from previously observed quark-number scaling is observed at large values of KE T/n q in noncentral Au+Au collisions (20-60%), but this scaling remains valid in central collisions (0-10%). © 2012 American Physical Society.
