Abstract
In a study of the reactionK−p →K-π−π+p at 10 and 16 GeV/c the one-pion-exchange model was tested by attempting to extract on this basis the angular distributions for π+p elastic scattering and comparing to real π+p scattering. In thes-channel frame high order moments already appeared at relatively low mass. In general there are large discrepancies in both thes- andt-channel frames which remain after extrapolation to the pion pole and are related toQ− production. The structure of the decay angular distribution of theK−K- π- system produced in association with Δ++ is dominated by proton diffractive dissociation into Δ++π-.
