Multiplicity fluctuations in nuclear collisions at 158 A GeV

The system size dependence of multiplicity fluctuations of charged particles produced in nuclear collisions at 158A GeV was studied in the NA49 CERN experiment. The results indicate a non-monotonic dependence of the scaled variance of the multiplicity distribution with a maximum for semi-peripheral...

Descripción
Sumario:The system size dependence of multiplicity fluctuations of charged particles produced in nuclear collisions at 158A GeV was studied in the NA49 CERN experiment. The results indicate a non-monotonic dependence of the scaled variance of the multiplicity distribution with a maximum for semi-peripheral Pb+Pb interactions with number of projectile participants of about 35. This effect is not observed in a string-hadronic model of nuclear collision HIJING.
