Description

The pseudorapidity densities of charged particles and inclusive photons produced in high-energy nuclear collisions are essential observables to characterise the global properties of the collisions, such as the achieved energy density, and to provide important constraints for Monte Carlo model calculations. In the LHC Run 1 and Run 2 configurations, ALICE had large coverage to measure charged particles over wide pseudorapidity range $−3.4 < \eta < 5.0$, combining the coverage from the Silicon Pixel Detector (SPD) and the Forward Multiplicity Detector (FMD). The inclusive photons are measured at forward rapidity using the Photon Multiplicity Detector (PMD), covering the pseudorapidity range $2.3<\eta<3.9$. In addition, particle production mechanisms at the LHC are explored by addressing the charged-particle pseudorapidity densities measured in pp, p--Pb, and Pb--Pb collisions and the rapidity densities of inclusive photons in pp and p-Pb collisions using LHC Run 1 and 2 data. The new performance results for ALICE Run 3 configuration are also presented to exploit the upgrade detectors setup.
