Comparison of the Near-Threshold Production of eta- and K-Mesons in Proton-Proton Collisions
Goran Faldt, Colin Wilkin
Abstract
The pp -> pp eta and pp -> pLambda K+ 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.
