Multiparticle correlations: prospects for ISABELLE

Exploring the systematics of hadron production in many-body final states is essential to an experimental program whose aim is to address the nature of strong interaction processes (broadly, the term multiparticle correlations includes such investigations). Historically, a great deal of effort has gone into these exporations for as long as high energy collision data have been available for study, and considerable physics insight has been gained despite the enormous kinematic complexity of the typical inelastic collision. Progress has been made by summing over most of the complications and investigating those features which appear to be most revealing and amenable to theoretical interpretation. The connection with theory is through phenomenological constructions which embody the ingredients of theories and are parameterized in terms of the measured properties of simpler processes. At ISABELLE, these pursuits will be part of a larger program in which we expect to examine directly fundamental processes about which we have thus far only speculated. Present models cannot be simply extrapolated as a reliable guide to the most interesting aspects of multiparticle data at the new energies. A discussion is given of some aspects of multiparticle analysis and recent experimental data which seem to be of particular importance in the consideration of new investigations at ISABELLE. The discussion includes some consideration of detection capability, emphasizing the need among the first experiments for accurate measurements of charged particle production over the full solid angle and assuming the eventual presence of very sophisticated multiparticle spectrometer facilities
