| Abstract: | The reactionsπ ? p→K 0(890) Λ,K 0(890)Σ 0 andK 0(890)Σ 0 are studied at an incident momentum of 3.95 GeV/c using data from a high statistics bubble chamber experiment corresponding to ～90 events/μb. The differential cross sections, density matrix elements of the vector meson and hyperon polarizations are presented. A transversity amplitude analysis is performed for each of the reactions. The results are compared with those obtained for the SU(3) related processesK ? p→?Δ, ?Σ 0, ?Σ 0(1385) and? ? Σ +(1385) and with predictions of the additive quark model and SU(6) sum rules. |
