Coupled channel Faddeev calculations of a image quasibound state

The image system is studied using separable interactions fitted to data available on the s-wave image–πY subsystem and the p-wave πN, πY, ππ and image subsystems. Three-body image–πYπ coupled channel Faddeev equations with relativistic kinematics are solved in search for poles in the complex energy plane. A image quasibound pole with quantum numbers image is found near and below the image threshold, its precise location depending sensitively on the poorly known shape of the p-wave πY interaction. This image quasibound state suggests the existence of a image Σ resonance with width about 60 MeV near threshold (image), excluding meson absorption contributions.
