Multiplicity of charged particles in Pb-Pb collisions at SPS energies

Περίληψη:

The multiplicity of charged particles in the central rapidity region has
been measured by the NA57 experiment in Pb-Pb collisions at the CERN SPS
at two beam momenta: 158 A GeV/c and 40 A GeV/c. The value of dN(ch)/d
eta at the maximum has been determined and its behaviour as a function
of centrality has been studied in the centrality range covered by NA57
(about 50% of the inelastic cross section). The multiplicity increase
is compatible with a logarithmic dependence on the centre of mass
energy. The results are compared with those from other experiments and
with the VENUS and RQMD models.
