Pseudorapidity distributions of charged particles in Pb-Pb collisions at super proton synchrotron energies from the NA50 experiment
We present the measurements of charged particle pseudorapidity distributions $dN\_{ch}/d \eta$ performed by the NA50 experiment in Pb-Pb collisions at the CERN SPS. Measurements were done at incident energies of 40 GeV ($\sqrt{s}$ = 8.77 GeV) and 158 GeV ($\sqrt{s}$ = 17.3 GeV) per nucleon over a br...

| description | We present the measurements of charged particle pseudorapidity distributions $dN\_{ch}/d \eta$ performed by the NA50 experiment in Pb-Pb collisions at the CERN SPS. Measurements were done at incident energies of 40 GeV ($\sqrt{s}$ = 8.77 GeV) and 158 GeV ($\sqrt{s}$ = 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 $\sqrt{s}$ = 8.77 GeV and $\sqrt{s}$ = 17.3 GeV. (5 refs). |
