High-statistics measurements were performed at LHC, with the ALICE central barrel detectors, in the central pseudorapidity region (–1 ≤ η < 1) of multiplicity distributions, and pseudorapidity densities of primary charged particles produced in proton–proton collisions, at √s = 0.9 TeV, 2.76 TeV and 7 TeV. Measurements were obtained for two event classes: inelastic events (INEL) and non-single diffractive events (NSD). The data are compared to measurements from other experiments and to simulations with Monte Carlo event generators PYTHIA and PHOJET.
