The impact of final-state interaction on the πΣ photoproduction in the Λ(1405) region

Abstract

It was recently demonstrated [1] that the meson-baryon rescattering in the final state has a major impact on the magnitude and structure of the πΣ mass distributions observed in the γp → K+πΣ photoproduction. We discuss briefly several aspects of this work emphasizing the model dependence of the meson-baryon amplitudes, used to represent the final-state interaction, and the role of the adopted photoproduction mechanism.
