Charged-particle multiplicities at different pp interaction centre-of-mass energies measured with the ATLAS detector at the LHC

Measurements are presented from proton-proton collisions at different centre-of-mass energies in the range of 0.9 to 13 TeV recorded with the ATLAS detector at the LHC. The charged-particle multiplicity, its dependence on transverse momentum and pseudorapidity, and the relationship between the mean transverse momentum and charged-particle multiplicity are measured. The results are corrected for detector effects and are presented at the particle-level. The results are compared to various Monte Carlo event generator models.
