Multiplicity dependence of identical particle correlations in the quantum optical approach - art. no. 034903

Identical particle correlations at fixed multiplicity are considered in the presence of chaotic and coherent fields. The multiplicity distribution, on e-particle momentum density, and two-particle correlation function are obta ined based on the diagrammatic representation for cumulants in semi-inclusi ve events. Our formulation is applied to the analysis of the experimental d ata on the multiplicity dependence of correlation functions reported by the UA1 and the OPAL Collaborations. [S0556-2813(99)07008-9].
