title: "Figure 5" of "Photon and neutral pion production in Au + Au collisions at s(NN)**(1/2) = 130-GeV."

description: dE/dx deviant distributions of positive daughters
description: We report the first inclusive photon measurements about mid-rapidity (|y|&lt;0.5) from Au+Au collisions at sqrt(s_{NN}) = 130 GeV at RHIC. Photon pair conversions were reconstructed from electron and positron tracks measured with the Time Projection Chamber (TPC) of the STAR experiment. With this method, an energy resolution of Delta(E)/E = 2% at 0.5 GeV has been achieved. Reconstructed photons have also been used to measure the transverse momentum (pt) spectra of pi0 mesons about mid-rapidity (|y|&lt;1) via the pi0 -&gt; photon photon decay channel. The fractional contribution of the pi0 -&gt; photon photon decay to the inclusive photon spectrum decreases by 20% +/- 5% between pt = 1.65 GeV/c and pt = 2.4 GeV/c in the most central events, indicating that relative to pi0 -&gt; photon photon decay the contribution of other photon sources is substantially increasing.

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

description: Correlation between the event plane angles determined from pairs of subevents partitioned randomly (circles), partitioned with opposite signs of pseudorapidity (squares) and partitioned with opposite signs of charge (crosses). The correlation is plotted as a function of centrality, namely, charged particle multiplicity $n_{ch}$ divided by the maximum observed charged multiplicity, $n_{max}$.
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.
