Abstract
A model calculation for the reactions pp pΛK+ and pp NΣK near their thresholds is presented. It is argued that the experimentally observed strong suppression of Σ0 production compared to Λ production at the same excess energy could be due to a destructive interference between the π and K exchange contributions in the reaction pp pΣ0 K+. Predictions for pp pΣ+ K0 and pp nΣ+ K+ are given.
