Differential cross sections and polarizations have been measured for the reaction π − p → K 0 Λ and π − p → K 0 Σ 0 at 3.9 GeV/ c π − momentum. Comparison of these data with those of the related reactions K − n → π − Λ and K − p → π − Σ + (at approximately the same c.m. energy) indicate that simple Regge-pole models involving only K ∗ (890) and K ∗ (1420) exchange are unable to describe all the features of the data. On the other hand, comparison of the π − p → K 0 Σ 0 data with that of π + p → K + Σ + shows that the data are consistent with absence of exotic strange-meson exchange.

Study of the Reactions $\pi^- p \to K^0 \Lambda$ and $\pi^- p \to K^0 \Sigma^0$ at 3.95-{GeV}/$c$

The CERN-College de France-Madrid-Stockholm collaboration Loverre, P.F. ; Armenteros, R. ; Dionisi, C. ; et al.
Z.Phys.C 6 (1980) 283, 1980.
Inspire Record 153918 DOI 10.17182/hepdata.14374

The reactions π−p→K0Λ,K0Σ0 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 and hyperon polarizations are presented and compared with existing data from earlier electronic experiments. The data in the forward hemisphere are used to perform an amplitude analysis of the 0−1/2+→0−1/2+ hypercharge exchange processes.
