Abstract

Differential cross sections are presented for the reactions K^-p → Λω, K^-p → Λφ{symbol}, K^-n → Σ^-ω and K^-N → Σ^-φ{symbol} at 3 GeV/c incident momentum. Significant backward peaks are observed in the reactions giving ω-meson production in contrast to the reactions with φ{symbol}-meson production. The assumption that the backward peaks observed are due to nucleon exchange leads to a ratio of the coupling constants g_ΣNK²/g_ΛNK² which is in disagreement with the prediction of SU(6) for this ratio.
