Description

The reactions pp→pΛK+ and pp→pΣ0K+ are studied near their thresholds. The strangeness production process is described by the π- and K exchange mechanisms. Effects from the final state interaction in the hyperon-nucleon system are taken into account rigorously. It is shown that the experimentally observed strong suppression of Σ0 production compared to Λ production can be explained by a destructive interference between π and K exchange in the reaction pp→pΣ0K+
