title: "Figure 13.2" of "High transverse momentum eta meson production in p+p, d+Au and Au+Au collisions at S(NN)**(1/2) = 200-GeV"

description: Inelastic cross section measured in d+Au at $\sqrt{s}$=200 GeV through $\eta \rightarrow \pi^{0} \pi^{+} \pi^{-}$
description: BNL-RHIC. Inclusive transverse momentum spectra of $\eta$ mesons in the range $p_T\approx$ 2-12 GeV/$c$ have been measured at mid-rapidity (|$\eta$| &lt; 0.35) by the PHENIX experiment at RHIC in p+p, d+Au and Au+Au collisions at $\sqrt{s_{NN}}$ = 200 GeV. The $\eta$ mesons are reconstructed through their $\eta\rightarrow\gamma\gamma$ channel for the three colliding systems as well as through the $\eta\rightarrow\pi^{0}\pi^{+}\pi^{-}$ decay mode in p+p and d+Au collisions. The nuclear modification factor in d+Au collisions, $R_{dAu}(p_T)\approx$ 1.0-1.1, suggests at most only modest $p_T$ broadening ("Cronin enhancement"). In central Au+Au reactions, the $\eta$ yields are significantly suppressed, with $R_{AuAu}(p_T)\approx$ 0.2. The ratio of $\eta$ to $\pi^{0}$ yields is approximately constant as a function of $p_T$ for the three colliding systems in agreement with the high-$p_T$ world average of $R_{\eta/\pi^{0}}\approx$ 0.5 in hadron-hadron, hadron-nucleus, and nucleus-nucleus collisions for a wide range of center-of-mass energies [$\sqrt{s_{NN}}\approx$ 3-1800 GeV] as well as, for high scaled momentum $x_p$, in $e^{+}e^{-}$ annihilations at $\sqrt{s}$ = 91.2 GeV. These results are consistent with a scenario where high-$p_T$ $\eta$ production in nuclear collisions at RHIC is largely unaffected by initial-state effects, but where light-quark mesons ($\pi^{0}$;$\eta$) are equally suppressed due to final-state interactions of the parent partons in the dense medium produced in Au+Au reactions.

title: "cfs" of "Suppression of away-side jet fragments with respect to the reaction plane in Au+Au collisions at sqrt(s_NN) = 200 GeV"

description: Delta phi / Correlation Function 3-4 GeV/c partners
description: BNL-RHIC. Pair correlations between large transverse momentum neutral pion triggers (pT= 4–7 GeV/c) andcharged hadron partners (pT= 3–7 GeV/c) in central (0–20%) and midcentral (20–60%) Au+Aucollisions are presented as a function of trigger orientation with respect to the reaction plane. Theparticles are at larger momentum than where jet shape modifications have been observed, and thecorrelations are sensitive to the energy loss of partons traveling through hot dense matter. An out-of-plane trigger particle produces only 26±20% of the away-side pairs that are observed opposite ofan in-plane trigger particle. In contrast, near-side jet fragments are consistent with no suppressionor dependence on trigger orientation with respect to the reaction plane. These observations arequalitatively consistent with a picture of little near-side parton energy loss either due to surface biasor fluctuations and increased away-side parton energy loss due to a long path through the medium.The away-side suppression as a function of reaction-plane angle is shown to be sensitive to both theenergy loss mechanism in and the space-time evolution of heavy-ion collisions.
