Event-by-event Analysis of Na49 Central Pb-Pb Data

  • Thomas A. Trainor


Event-by-event analysis of nuclear collisions looks for differential manifestations of increased correlation or symmetry reduction in the multiparticle final state with respect to a minimally correlated (equilibrated) reference system. Event-by-event physics has been an active field of nuclear research for almost two decades, msinly emphasizing flow and jet studies. Jet production stems from interaction of partonic degrees of freedom at small space-time scales. Jet phenomena therefore reveal aspects of perturbative QCD. Flow reflects large-scale correlations between momentum and configuration space in the hadronic regime at later times. Jets and flow are ‘large-amplitude’ phenomena, observable even with low-multiplicity collision svstems.
