EVENT BY EVENT AVERAGES IN HEAVY ION COLLISIONS.

PDF Version Also Available for Download.

Description

Na49 (Pb+Pb, CERN), PHENIX and STAR (Au+Au, BNL) have presented measurements of the event-by-event average p{sub T} (denoted M{sub pT}) in relativistic heavy ion collisions. Event-by-event averages are most useful to resolve the case of two or several classes of events with e.g. different temperature parameters. The distribution of M{sub pT} is discussed, with emphasis on the case of statistically independent emission according to the semi-inclusive p{sub T} and charged multiplicity distributions. Deviations from statistically independent emission are quantified in terms of a simple two component model, with the individual components being Gamma distributions.
