Multiplicity dependence of identical particle correlations in the quantum optical approach
N. Suzuki, M. Biyajima · Physical Review C · 1999
Identical particle correlations at fixed multiplicity are considered in the presence of chaotic and coherent fields. The multiplicity distribution, one-particle momentum density, and two-particle correlation function are obtained based on the diagrammatic representation for cumulants in semi-inclusive events. Our formulation is applied to the analysis of the experimental data on the multiplicity dependence of correlation functions reported by the UA1 and the OPAL Collaborations.
