title: "jfsall_20-60 5-7" of "Suppression of away-side jet fragments with respect to the reaction plane in Au+Au collisions at sqrt(s_NN) = 200 GeV"

description: $p^{a}_{T} = 5-7$ GeV/$c$
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.

title: "fig1a1" of "Evolution of pi^0 suppression in Au+Au collisions from sqrt(s_NN) = 39 to 200 GeV"

description: INVARIANT YIELDS
description: BNL-RHIC. Neutral-pion, $\pi^0$, spectra were measured at midrapidity ($|y| &lt; 0.35$) in Au+Au collisions at $\sqrt{sNN}=$ 39 and 62.4 GeV and compared to earlier measurements at 200 GeV in the $1 &lt; p_T &lt; 10$ GeV/c transverse-momentum ($p_T$) range. The high-$p_T$ tail is well described by a power law in all cases and the powers decrease significantly with decreasing center-of-mass energy. The change of powers is very similar to that observed in the corresponding p+p-collision spectra. The nuclear-modification factors (RAA) show significant suppression and a distinct energy dependence at moderate $p_T$ in central collisions. At high $p_T$, RAA is similar for 62.4 and 200 GeV at all centralities. Perturbative-quantumchromodynamics calculations that describe RAA well at 200 GeV, fail to describe the 39 GeV data, raising the possibility that the relative importance of initial-state effects and soft processes increases at lower energies. A conclusion that the region where hard processes are dominant is reached only at higher $p_T$, is also supported by the $x_T$ dependence of the $x_T$-scaling power-law exponent.

title: "Figure 7-1" of "Azimuthal anisotropy of pi^0 and eta mesons in Au+Au collisions at sqrt(s_NN)=200 GeV"

description: $\eta$ meson $v_2, 0-20\%$ centrality
description: BNL-RHIC. The azimuthal anisotropy coefficients $v_2$ and $v_4$ of $\pi^0$ and $\eta$ mesons are measured in Au+Au collisions at $\sqrt{s_NN}$=200 GeV, as a function of transverse momentum $p_T$ (1-14 GeV/c) and centrality. The extracted $v_2$ coefficients are found to be consistent between the two meson species over the measured $p_T$ range. The ratio of $v_4/v_2^2$ for $\pi^0$ mesons is found to be independent of $p_T$ for 1-9 GeV/$c$, implying a lack of sensitivity of the ratio to the change of underlying physics with $p_T$. Furthermore, the ratio of $v_4/v_2^2$ is systematically larger in central collisions, which may reflect the combined effects of fluctuations in the initial collision geometry and finite viscosity in the evolving medium.
