Sažetak
Net proton and negative hadron spectra for central PbPb collisions at 158 GeV per nucleon at the CERN SPS were measured and compared to spectra from lighter systems. Net baryon distributions were derived from those of net protons, utilizing model calculations of isospin contributions as well as data and model calculations of strange baryon distributions. Stopping (rapidity shift with respect to the beam) and mean transverse momentum meanpt of net baryons increase with system size. The rapidity density of negative hadrons scales with the number of participant nucleons for nuclear collisions, whereas their meanpt is independent of system size. The meanpt dependence upon particle mass and system size is consistent with larger transverse flow velocity at midrapidity for PbPb compared to SS central collisions.
