Scaling and correlations of squeezed coherent distributions: Application to hadronic multiplicities

Abstract

It is shown that a k-mode squeezed-coherent-state distribution is the most general one in describing hadronic multiplicity distributions in particle collision processes. An exact expression for the k-mode squeezed coherent multiplicity distribution is derived. The properties of this distribution are compared with the Glauber-Lachs distribution and it is shown that pure squeezed states show asymptotic scaling. The correlation properties of this distribution are shown and its usefulness in pion-interferometry experiments is discussed. The domain of reach of these states is shown to be wider than that of the Glauber-Lachs distribution. © 1988 The American Physical Society.
