PARTICLE PRODUCTION AND FLUCTUATIONS IN 158 GeV/n Pb COLLISIONS WITH NUCLEAR TARGETS

摘要

Results from the CERN EMU13 experiment on particle multiplicities and pseu-dorapidity distributions are shown for semi-central Pb-Ag/Br and Pb-Pb colli-sions. Superposition models provide a good description of these global observ-ables. However, the analysis of fluctuations revealed the presence of dynamical -fluctuations, in contrast to the VENUS model expectations. The investigation of fluctuations in individual high multiplicity events is presented.
