title: "Table 9e" of "Elliptic flow from two- and four-particle correlations in Au + Au collisions at s(NN)**(1/2) = 130-GeV."

description: Reconstructed $v_{2}$ vs $p_{t}$ from the conventional method (circles), from the second-order cumulant method (triangles), and from the fourth-order cumulant method (stars), in eight centrality bins. The upper left panel shows the most peripheral events, and the lower right the most central.
description: Elliptic flow holds much promise for studying the early-time thermalization attained in ultrarelativistic nuclear collisions. Flow measurements also provide a means of distinguishing between hydrodynamic models and calculations which approach the low density (dilute gas) limit. Among the effects that can complicate the interpretation of elliptic flow measurements are azimuthal correlations that are unrelated to the reaction plane ( nonflow correlations). Using data for $Au+Au$ collisions at $\sqrt{s_{NN}}=130$ GeV from the STAR time projection chamber, it is found that four-particle correlation analyses can reliably separate flow and nonflow correlation signals. The latter account for on average about $15\%$ of the observed second-harmonic azimuthal correlation, with the largest relative contribution for the most peripheral and the most central collisions. The results are also corrected for the effect of flow variations within centrality bins. This effect is negligible for all but the most central bin, where the correction to the elliptic flow is about a factor of 2. A simple new method for twoparticle flow analysis based on scalar products is described. An analysis based on the distribution of the magnitude of the flow vector is also described.

title: "Table 14" of "Elliptic flow from two- and four-particle correlations in Au + Au collisions at s(NN)**(1/2) = 130-GeV."

description: $v_{2}/\varepsilon$ as a function of charged particle density in $Au+Au$ collisions. Data are from E877 at the AGS (squares), NA49 at the SPS (circles), and STAR at RHIC (stars). The AGS and SPS data have been obtained by conventional flow analysis. The STAR measurements are at $\sqrt{s_{NN}}=130$ GeV, and correspond to the final corrected elliptic flow based on fourth-order cumulants, and we assume $dN/dy=1.15dN/d\eta$. The horizontal shaded bands indicate the hydrodynamic limits for different beam energies [44].

title: "Table 1" of "Proton Lambda correlations in central Au + Au collisions at s(NN)**(1/2) = 200-GeV."

description: Invariant mass of the selected $\Lambda$ background not substracted with $0.3 &lt; p_t &lt; 2.0$ GeV/c. The y axis represents the number of candidates used in this analysis.
description: We report on $p-\Lambda$, $p-\bar{\Lambda}$, $\bar{p}-\Lambda$, and $\bar{p}-\bar{\Lambda}$ correlation functions constructed in central $Au-Au$ collisions at $\sqrt{s_{NN}}=200$ GeV by the STAR experiment at RHIC. The proton and lambda source size is inferred from the $p-\Lambda$ and $\bar{p}-\bar{\Lambda}$ correlation functions. It is found to be smaller than the pion source size also measured by the STAR experiment at smaller transverse masses, in agreement with a scenario of a strong universal collective flow. The $p-\bar{\Lambda}$ and $\bar{p}-\Lambda$ correlation functions, which are measured for the first time, exhibit a large anticorrelation. Annihilation channels and/or a negative real part of the spin-averaged scattering length must be included in the final-state interactions calculation to reproduce the measured correlation function.
