title: "Table 2" of "Near-side azimuthal and pseudorapidity correlations using neutral strange baryons and mesons in d+Au, Cu+Cu and Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV"

description: Corrected correlation functions $\frac{dN_{J}}{d\Delta\eta}$ in $\mid$$\Delta\eta$$\mid&lt;$ 0.78 for 3 &lt; $p_T^{trigger}$ &lt; 6 GeV/$c$ and 1.5 GeV/$c$ &lt; $p_T^{associated}$ &lt; $p_T^{trigger}$ for (a) $\Lambda$-h and (b) $K_S^0$-h for minimum bias $d$+Au, 0-20% Cu+Cu, and 40-80% Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV after background subtraction. The data have been reflected about $\Delta\eta$ = 0.
description: BNL-RHIC. We present measurements of the near-side of triggered di-hadron correlations using neutral strange baryons ($\Lambda$, $\bar{\Lambda}$) and mesons ($K^0_S$) at intermediate transverse momentum (3 $&lt;$ $p_T$ $&lt;$ 6 GeV/$c$) to look for possible flavor and baryon/meson dependence. This study is performed in $d$+Au, Cu+Cu and Au+Au collisions at $\sqrt{s_{{NN}}}$ = 200 GeV measured by the STAR experiment at RHIC. The near-side di-hadron correlation contains two structures, a peak which is narrow in azimuth and pseudorapidity consistent with correlations due to jet fragmentation, and a correlation in azimuth which is broad in pseudorapidity. The particle composition of the jet-like correlation is determined using identified associated particles. The dependence of the conditional yield of the jet-like correlation on the trigger particle momentum, associated particle momentum, and centrality for correlations with unidentified trigger particles are presented. The neutral strange particle composition in jet-like correlations with unidentified charged particle triggers is not well described by PYTHIA. However, the yield of unidentified particles in jet-like correlations with neutral strange particle triggers is described reasonably well by the same model.

title: "Table 2" of "Dilepton mass spectra in p+p collisions at sqrt(s)= 200 GeV and the contribution from open charm"

description: Total charm cross section An additional systemactic error of +- 200 microbarn, due to the validity of the model used to extrapolate the data, is not included. To obtain the total charm cross section, the differential charm cross section has been extrapolated to the whole rapidity range, using a HVQMNR rapidity distribution with aCTEQ5M PDF.
description: Measurement at the PHENIX experiment of the electrons-positron pair mass spetrum from 0 to 8 Gev/c^2 in p+p collisions at center-of-mass energy of 200 GeV The contributions from light mesons decays to e+e- pairs have been determined using measurements of hadron production cross sections by PHENIX. After subtracting thiscontribution, the e+e- pair yield is dominated by semileptonic decay of charmed hadrons.

title: "Table 1" of "Observation of the Dalitz Decay $\eta' \to \gamma e^+e^-$"

description: Fitted ($n^{\text{obs}}_i$) and efficiency-corrected ($n^{\text{corr}}_i$) signal yields for the eight $M(e^+e^-)$ bins, and ratios ($r_i$). The uncertainties are statistical only.
description: BEPC-BES. We report the first observation of the Dalitz decay $\eta^\prime \to \gamma e^+e^-$, based on a data sample of 1.31 billion $J/\psi$ events collected with the BESIII detector. The $\eta^\prime$ mesons are produced via the $J/\psi \to \gamma \eta^\prime$ decay process. The ratio $\Gamma(\eta^\prime \to \gamma e^+ e^-)/\Gamma(\eta^\prime\to\gamma\gamma)$ is measured to be $(2.13\pm0.09(\text{stat.})\pm0.07(\text{sys.}))\times10^{-2}$. This corresponds to a branching fraction ${\cal B}(\eta^\prime \to \gamma e^+e^-)= (4.69 \pm0.20(\text{stat.})\pm0.23(\text{sys.}))\times10^{-4}$. The transition form factor is extracted and different expressions are compared to the measured dependence on the $e^+e^-$ invariant mass. The results are consistent with the prediction of the Vector Meson Dominance model.

description: BNL-RHIC. We present an analysis of di-hadron correlations using recently developed methods for background subtraction which allow for higher precision measurements with fewer assumptions about the background. These studies indicate that low momentum jets interacting with the medium do not equilibrate with the medium, but rather that interactions with the medium lead to more subtle increases in their widths and fragmentation functions, consistent with observations from studies of higher momentum fully reconstructed jets. The away-side shape is not consistent with a Mach cone.
