Description
An overview of the measured pseudorapidity densities and multiplicity distributions
at the LHC's Run 1 and 2 energies will be presented for pp, p-Pb and Pb-Pb systems.
The ALICE results are shown for central pseudorapidities and, if available, over a
wider pseudorapidity range (-3.4 < η < 5.0).
The measurement of the inclusive charged-particle production in high-energy interactions
is a fundamental observable to describe the global characteristics of the collision.
Particle production at LHC energies is dominated by soft processes, but with increasing
collision energy the role of perturbative hard processes, like parton scatterings, grows.
The ALICE measurements are compared with results of the dierent LHC and RHIC
experiments. The evolution of the multiplicity with energy is studied, utilizing different parameters depending on the colliding system considered. In addition, the results are
compared to models based on various mechanisms of particle production and different
initial conditions.
