Abstract

We present the measurements of charged particle pseudorapidity distributions dN_ch/dη performed by the NA50 experiment in Pb-Pb collisions at the CERN SPS. Measurements were done at incident energies of 40 GeV (√s = 8.77 GeV) and 158 GeV (√s = 17.3 GeV) per nucleon over a broad impact parameter range. The multiplicity distributions are studied as a function of centrality using the number of participating nucleons (N_part), or the number of binary nucleon-nucleon collisions (N_coll). Their values at midrapidity exhibit a linear scaling with N_part at both energies. Particle yield increases approximately by a factor of 2 between √s = 8.77 GeV and √s = 17.3 GeV.

Measurements were done at incident energies of 40 GeV (√s = 8.77 GeV) and 158 GeV (√s = 17.3 GeV) per nucleon over a broad impact parameter range. The multiplicity distributions are studied as a function of centrality using the number of participating nucleons (Npart), or the number of binary nucleon-nucleon collisions (Ncoll). Their values at midrapidity exhibit a linear scaling with Npart at both energies. Particle yield increases approximately by a factor of 2 between √s = 8.77 GeV and √s = 17.3 GeV.
