Final State Interactions in the Near-Threshold Production of Kaons from Proton-Proton Collisions
Abstract
Description
We analyse the $pp \to p ΛK$ cross section recently measured at COSY arguing that the enhancement of the production cross section at energies close to the reaction threshold should be due to the $Λp$ final state interaction. We find that the experimental $Λp$ elastic scattering data as well as the predictions from the Jülich-Bonn model are in reasonable agreement with the new results on $K^+$-meson production. We propose to study directly the final state interaction by measurements of the cross section as a function of the hyperon momentum in the $Λp$ cm system.
