Measurements of high $p_T$ identified particles $v_2$ and $v_4$ in $\sqrt{s_{NN}}=200$ GeV Au+Au collisions by PHENIX

Abstract

The $v_2$ and $v_4$ of pions, kaons and protons have been measured by PHENIX in 200 GeV Au+Au collisions up to $p_T$$\sim$6 GeV/c and 4 GeV/c, respectively. The $v_4$ of all these identified particles have been found to scale with the number of constituent quarks and all these particles have a similar $v_4$/$v_2^2$ ratio which is close to 0.9. The scaling behavior of $v_2$ is studied at high-$p_T$ and a deviations from the universal scaling is observed for transverse kinetic energy ($K_{ET}/nq$) higher than 1 GeV.
