Resonance production and clustering effects in reactions K−p → Λ0 + pions at an incident beam momentum 8.25 GeV/c

We have estimated cross sections for the production of resonances in the reactions K−p → Λ0 + pions. The data have also been analysed by a method which examines event-to-event fluctuations. Within the framework of the simple parametrization of resonance production assumed, the contribution from the resonances is insufficient to explain the observed fluctuations in the longitudinal emission of the final-state particles. These features are well reproduced by an independent cluster emission model.
