Abstract:
An analysis of the Λpp system produced forward in the reaction Kp → Λpp at 18.5 GeV/c is presented. The data come from an experiment using the CERN Ω′ spectrometer. Structures are observed in the Λp mass spectrum and in the double moments HLMlm describing the decay of the Λp system and the subsequent Λ decay, for L ≤ 8. A partial wave analysis interprets these structures as resonances of spin parities 2- and 3+, masses and widths M = 2200 ± 40 MeV, Γ = 150 ± 30 MeV and M = 2330 ± 40 MeV, Γ = 150 ± 30 MeV respectively.
