The system size and centrality dependence of multiplicity fluctuations in nuclear collisions at 158A GeV as well as the energy dependence for the most central Pb + Pb collisions were studied by the NA49 experiment at CERN SPS. A strong increase of fluctuations was observed with decreasing centrality in C + C, Si + Si and Pb + Pb collisions. The string hadronic models (UrQMD, Venus, HIJING, HSD) can not reproduce the observed increase. This may indicate a strong mixing of target and projectile… Expand
