INTEGRAL CORRELATION MEASURES FOR MULTIPARTICLE PHYSICS

We report on a considerable improvement in the technique of measuring multiparticle correlations via integrals over correlation functions. A modification of measures used in the characterization of chaotic dyna mical systems permits fast and flexible calculation of factorial momen ts and cumulants as well as their differential versions. Higher-order correlation integral measurements even of large multiplicity events su ch as encountered in heavy ion collisons are now feasible. The change from ''ordinary'' to ''factorial'' powers may have important consequen ces in other fields such as the study of galaxy correlations and Bose- Einstein interferometry.
