EVENT-BY-EVENT ANALYSIS OF HEAVY-ION COLLISIONS AND THERMODYNAMICAL FLUCTUATIONS

An event-by-event analysis of heavy ions collisions is becoming possib le with advent of large acceptance detectors. Such analysis can provid e dynamical information which cannot be obtained from inclusive spectr a. We identify some observables which can be related to the standard t heory of thermodynamic fluctuations and which may provide information about the properties of hadronic matter at the freeze-out stage. Among those are fluctuations of ''apparent temperature'', or the p(t) slope , and the population of different bins of the pion momentum distributi on. (C) 1998 Published by Elsevier Science B.V.
