title: "Figure 10b-3" of "Deviation from quark-number scaling of the anisotropy parameter v_2 of pions, kaons, and protons in Au+Au collisions at sqrt(s_NN) = 200 GeV"

description: The quark-number-scaled $v_2$ ($v_2/n_q$) of identified hadrons are shown as a function of the kinetic energy per quark, KE$_T/n_q$ in 10–40% centrality [panel (b)] in Au + Au collisions at $\sqrt{s_{NN}}$ = 200 GeV. The $v_2$ of $\Lambda$ and K$^0_S$ are measured by STAR collaboration [21]. The error bars (open boxes) represent the statistical (systematic) uncertainties. The systematic uncertainties shown on the results from this study are type A and B only.
description: 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 (|$\eta$| &lt; 0.35) in Au + Au collisions at $\sqrt{s_{NN}}$ =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 Cerenkov detectors in the PHENIX ˇExperiment. 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%).

title: "Table 2" of "Centrality dependence of the high p(T) charged hadron suppression in Au + Au collisions at s(NN)**(1/2) = 130-GeV."

description: Number of participants and binary collisions and their systematic errors for the individual centrality selections used in this analysis. Also given is the ratio of the number of binary collisions for the most central sample relative to the one for each sample. The last column quantifies the ratio of binary collisions to participant pairs.
description: PHENIX has measured the centrality dependence of charged hadron $p_T$ spectra from Au + Au collisions at $\sqrt{s_{NN}}$ = 130 GeV. The truncated mean $p_T$ decreases with centrality for $p_T$ $&gt;$ 2 GeV/$c$, indicating an apparent reduction of the contribution from hard scattering to high $p_T$ hadron production. For central collisions the yield at high $p_T$ is shown to be suppressed compared to binary nucleon-nucleon collision scaling of p+p data. This suppression is monotonically increasing with centrality, but most of the change occurs below 30% centrality, i.e. for collisions with less than $~$ 140 participating nucleons. The observed $p_T$ and centrality dependence is consistent with the particle production predicted by models including hard scattering and subsequent energy loss of the scattered partons in the dense matter created in the collisions.
