Combined analysis of K−p reactions and πΣ photoproduction data

Abstract

We discuss results of a simultaneous fit to the K−p reactions and πΣ photoproduction data employing an approach that combines tree level photoproduction amplitudes with πΣ − KN coupled channel model describing the meson-baryon rescattering in the final state. The achieved reproduction of the photoproduction mass distributions represents a significant improvement when compared with the parameter free predictions made earlier but remains inferior to more comprehensive models that employ much larger sets of adjustable parameters.
