title: "$I_{AA}$ Ratio fig5a" of "Photon-Hadron Jet Correlations in p+p and Au+Au Collisions at sqrt(s_NN) = 200 GeV"

description: Ratio of $I_{AA}$ of Au+Au to p+p yields at 5&lt;$p_{T}^{\gamma}$&lt;7 GeV/c.
description: BNL-RHIC. We report the observation at the Relativistic Heavy Ion Collider (RHIC) of suppression of back-to-back correlations in the direct photon+jet channel in Au+Aurelative top+pcollisions. Two-particlecorrelations of direct photon triggers with associated hadrons are obtained by statistical subtractionof the decay photon-hadron (γ-h) background. The initial momentum of the away-side parton istightly constrained, because the parton-photon pair exactly balance in momentum at leading orderin perturbative quantum chromodynamics (pQCD), making such correlations a powerful probe ofthe in-medium parton energy loss. The away-side nuclear suppression factor,IAA, in central Au+Aucollisions, is 0.32±0.12stat±0.09systfor hadrons of 3&lt; phT&lt;5 in coincidence with photons of 5&lt; pγT&lt;15 GeV/c. The suppression is comparable to that observed forhigh-pTsingle hadronsand dihadrons. The direct photon associated yields inp+pcollisions scale approximately with themomentum balance,zT≡phT/pγT, as expected for a measure of the away-side parton fragmentationfunction. We compare to Au+Au collisions for which the momentum balance dependence of thenuclear modification should be sensitive to the path-lengthdependence of parton energy loss.

title: "fig1" of "Quantitative Constraints on the Opacity of Hot Partonic Matter from Semi-Inclusive Single High Transverse Momentum Pion Suppression in Au+Au collisions at sqrt(s_NN) = 200 GeV"

description: $\pi^0$ $0-5\%$ centrality
description: BNL-RHIC. The PHENIX experiment has measured the suppression of semi-inclusive single high transverse momentum $\pi^0$'s in Au+Au collisions at $\sqrt{sNN}=200$ GeV. The present understanding of this suppression is in terms of energy-loss of the parent (fragmenting) parton in a dense color-charge medium. We have performed a quantitative comparison between various parton energy-loss models and our experimental data. The statistical point-to-point uncorrelated as well as correlated systematic uncertainties are taken into account in the comparison. We detail this methodology and the resulting constraint on the model parameters, such as the initial color-charge density $dN^g/dy$, the medium transport coefficient $\langle \hat{q} \rangle$, or the initial energy-loss parameter $\epsilon_0$. We find that high transverse momentum $\pi^0$ suppression in Au+Au collisions has sufficient precision to constrain these model dependent parameters at the $\pm 20-25$\% (one standard deviation) level. These constraints include only the experimental uncertainties, and further studies are needed to compute the corresponding theoretical uncertainties.

title: "fig4" of "High-pT pi^zero Production with Respect to the Reaction Plane in Au + Au Collisions at sqrt(s_NN) = 200 GeV"

description: $\pi^0 v_2$ as function of centrality. All errors are absolute.
description: Measurements of the azimuthal anisotropy of high-$p_T$ neutral pion ($\pi^0$) production in Au+Au collisions at $\sqrt{sNN} = 200$ GeV by the PHENIX experiment are presented. The data included in this paper were collected during the 2004 RHIC running period and represent approximately an order of magnitude increase in the number of analyzed events relative to previously published results. Azimuthal angle distributions of $\pi^0$s detected in the PHENIX electromagnetic calorimeters are measured relative to the reaction plane determined event-by-event using the forward and backward beam-beam counters. Amplitudes of the second Fourier component ($v_2$) of the angular distributions are presented as a function of $\pi^0$ transverse momentum (pT) for different bins in collision centrality. Measured reaction plane dependent $\pi^0$ yields are used to determine the azimuthal dependence of the $\pi^0$ suppression as a function of pT, RAA(∆φ, pT). A jet-quenching motivated geometric analysis is presented that attempts to simultaneously describe the centrality dependence and reaction plane angle dependence of the $\pi^0$ suppression in terms of the path lengths of hypothetical parent partons 3 in the medium. This set of results allows for a detailed examination of the influence of geometry in the collision region, and of the interplay between collective flow and jet-quenching effects along the azimuthal axis.
