title: "Figure 6" of "Scaling properties of fractional momentum loss of high-pT hadrons in nucleus-nucleus collisions at $\sqrt{s_{_{NN}}}$ from 62.4 GeV to 2.76 TeV"

description: $p^{pp}_T$ dependence of $S_{loss}$ for $\pi^0$ in 62.4 GeV Cu+Cu collisions using the spectra measured by PHENIX in 2005.
description: 'Measurements of the fractional momentum loss ($S_{loss}$ ≡ $\delta p_T/p_T$) of high-transverse-momentum identified hadrons in heavy ion collisions are presented. Using $\pi^0$ in Au+Au and Cu+Cu collisions at $\sqrt{s_{NN}}$ = 62.4 and 200 GeV measured by the PHENIX experiment at the Relativistic Heavy Ion Collider and and charged hadrons in Pb+Pb collisions measured by the ALICE experiment at the Large Hadron Collider, we studied the scaling properties of $S_{loss}$ as a function of a number of variables: the number of participants, $N_{part}$, the number of quark participants, $N_{qp}$, the charged particle density, $dN_{ch}/d \eta$, and the Bjorken energy density times the equilibration time, $\epsilon B_j \tau_0$. We find that the $p_T$ , where Sloss has its maximum, varies both with centrality and collision energy. Above the maximum, Sloss tends to follow a power-law function with all four scaling variables. The data at $\sqrt{s_{NN}}$ = 200 GeV and 2.76 TeV, for sufficiently high particle densities, have a common scaling of $S_{loss}$ with $dN_{ch}/d \eta$ and $\epsilon B_j \tau_0$, lending insight on the physics of parton energy loss.'

title: "Fig. 1 — Mesons" of "Particle-species dependent modification of jet-induced correlations in Au+Au collisions at sqrt(s_NN) = 200 GeV"

description: Correlation functions for associated partner mesons for centrality selections of 20-40% and 70-90%. <i>Note that only statistical uncertainties are available.</i>
description: Measurements in $Au+Au$ collisions at $\sqrt{s_{NN}} = 200\ \mathrm{GeV}$ of jet correlations for a trigger hadron at intermediate transverse momentum ($p_{T,\ trig}$) with associated mesons or baryons at lower $p_{T,\ assoc}$ indicate strong modification of the away-side jet. The ratio of jet-associated baryons to mesons increases with centrality and $p_{T, assoc}$. For the most central collisions, the ratio is similar to that for inclusive measurements. This trend is incompatible with in-vacuum fragmentation but could be due to jetlike contributions from correlated soft partons, which recombine upon hadronization.

Comparisons of these observables with detailed theoretical calculations can be used to identify the nature of these interactions and to quantify their extent.
