${\rm d}\nch$/${\rm d}\eta$ vs. $\eta$ measurements: $\sqrt{s} = 2.76$ TeV compared with $\sqrt{s} = 2.36$ TeV taken from ALICE (top); $\sqrt{s}=$ 7 TeV and comparison with CMS and ALICE data (middle); $\sqrt{s} = 8$ TeV (bottom). Systematic uncertainties are shown as error bars for the previous data and as grey bands for the data from this publication. The scale is to be read off the right-hand side axis for INEL$>$0.
