 Values of $\dNdetape$ (top) and $\frac{2}{\langle N_\mathrm{part}\rangle} N^\mathrm{tot}_\mathrm{ch}$ (bottom) for the 5\% most central \XeXe\ collisions compared to previous measurements in \PbPb\ and \AuAu\ as a function of \snn, as well as for inelastic \pp, \ppbar\ and non-single diffractive pA and dA collisions The lines are power law fits to the data, excluding \XeXe\ results The central \PbPb\ measurements from CMS and ATLAS at \unit[2.76]{TeV} have been shifted horizontally for clarity.
