title: "Figure 2-2" of "Beam-energy and centrality dependence of direct-photon emission from ultra-relativistic heavy-ion collisions"

description: Number of binary collisions N_{coll} vs. centrality in Au+Au at various cm energies.
description: BNL-RHIC. The PHENIX collaboration presents first measurements of low-momentum (0.4&lt; $p_T$ &lt;3 GeV/$c$) direct-photon yields from Au+Au collisions at $\sqrt{s_{NN}}$=39 and 62.4 GeV. For both beam energies the direct-photon yields are substantially enhanced with respect to expectations from prompt processes, similar to the yields observed in Au+Au collisions at $\sqrt{s_{NN}}$=200. Analyzing the photon yield as a function of the experimental observable $dN_{ch}/d\eta$ reveals that the low-momentum (&gt;1 GeV/$c$) direct-photon yield $dN^{dir}_{\gamma}/d\eta$ is a smooth function of $dN_{ch}/d\eta$ and can be well described as proportional to $(dN_{ch}/d\eta)^\alpha$ with $\alpha\approx1.25$. This scaling behavior holds for a wide range of beam energies at the Relativistic Heavy Ion Collider and the Large Hadron Collider, for centrality selected samples, as well as for different, A+A collision systems. At a given beam energy the scaling also holds for high $p_T$(&gt;5 GeV/$c$) but when results from different collision energies are compared, an additional $\sqrt{s_{NN}}$-dependent multiplicative factor is needed to describe the integrated-direct-photon yield.

title: "Table 1.1" of "Production of muons from heavy-flavour hadron decays at high transverse momentum in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ and 2.76 TeV"

description: $p_{\rm T}$-differential yield of muons from heavy-flavour hadron decays at forward rapidity ($2.5 &lt; y &lt; 4$) for central (0--10%) and semi-central (20--40%) Pb--Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ TeV.
description: 'Measurements of the production of muons from heavy-flavour hadron decays in Pb-Pb collisions at $\sqrt{s_{\rm NN}}=5.02$ and $2.76$ TeV using the ALICE detector at the LHC are reported. The nuclear modification factor $R_{\rm AA}$ at $\sqrt{s_{\rm NN}}=5.02$ TeV is measured at forward rapidity ($2.5 &lt; y &lt;4$) as a function of transverse momentum $p_{\rm T}$ in central, semi-central, and peripheral collisions over a wide $p_{\rm T}$ interval, $3 &lt; p_{\rm T} &lt; 20$ GeV/$c$, in which a significant contribution of muons from beauty-hadron decays is expected at high $p_{\rm T}$. With a significantly improved precision compared to the measurements at lower collision energy, the $R_{\rm AA}$ shows an increase of the suppression of the yields of muons from heavy-flavour hadron decays with increasing centrality. A suppression by a factor of about three is observed in the $10\%$ most central collisions. The $R_{\rm AA}$ at $\sqrt{s_{\rm NN}}=5.02$ TeV is similar to that reported at $\sqrt{s_{\rm NN}}=2.76$ TeV in a broader $p_{\rm T}$ interval and with an improved accuracy with respect to previously published measurements. The precise $R_{\rm AA}$ results have the potential to distinguish between model predictions implementing different mechanisms of parton energy loss in the high-density medium formed in heavy-ion collisions. The results place stringent constraints on the relative energy loss between charm and beauty quarks.'
