 Comparison of $\langle$d$E_{\mathrm T}/$d$\eta \rangle / \langle N_{\mathrm{part}}/2\rangle$ at midrapidity in Pb-Pb collisions at ${\sqrt{s_{\mathrm {NN}}}}$ = 2.76 TeV from CMS and ALICE and in Au-Au collisions at ${\sqrt{s_{\mathrm {NN}}}}$ = 200 GeV from STAR and PHENIX. Data from RHIC were scaled by a factor of 2.7 for comparison of the shapes The boxes indicate the systematic uncertainties.
