Figure 1

Average pseudorapidity density of charged particles as a function of $\eta$ produced in pp collisions at $\sqrt{s}$ = 13 TeV. The ALICE results are shown in the normalisation classes INEL and INEL>0 and compared to Monte Carlo calculations [18,19,24,26-28] and to the results from the CMS Collaboration. The uncertainties are the quadratic sum of statistical and systematic contributions.
