Cross sections of the reaction K − p → π + π − π 0 Λ are determined in a bubble chamber study at 10 incoming beam momenta between 1.425 GeV/ c and 1.800 GeV/ c . For the subsample K − p → ωΛ , cross sections and angular distributions are presented together with their Legendre polynomial expansions and those of the single and joint density matrix elements. An energy dependent partial-wave analysis is performed including earlier data. The data is well fitted by constant background amplitudes in the outgoing S, P and D waves plus two I = 0 resonances in this region, the well established G 7 Λ(2100) and the P 3 Λ(1870).

We present complete results concerning the five reactions K − p → Λω , K − p → Λφ , K − p → Σ 0 ϱ and K − p → Σ 0 φ . The experimental data are well described by exchange mechanisms and the agreement with the SU(3) symmetry predictions is excellent.
