Abstract

The pp → ppη and pp → pΛK+ reactions near threshold are dominated by the first and second S11 resonance respectively. It is shown that a one-pion-exchange model exciting these isobars reproduces well the ratio of the production cross sections. The consequences for this and other channels are discussed.
