In an analysis of the reaction K − n →Λ4π at 3 GeV c we find evidence for the production of the B(1220) resonance, mainly decaying in ωπ. For the mass and width we find (1236 ± 15) MeV c 2 and (132±20) MeV c 2 respectively. The cross section for the reaction K − n→ Λ +B(1220) is found to be (102±26) μ b.

We present the results of a study of 1173 uniquely identified events of the K 0 π + p final state produced in 10 GeV/ c K + p interactions. This final state is dominated by the quasi two-body processes K + p → K 0 N ∗+ (890 p and K + p → K ∗+ (1420) p . The background is very low and there is little overlapping of resonance bands. We present cross sections, t -distributions and decay angular distributions for the contributing reaction channels. Dips are observed near t = 0 in the differential cross sections for all three processes.
