Title
Nucleon resonance decay by the Kappa(0)Sigma channel
Abstract
Hyperon production off the proton in the K0Sigma+ channel has been studied at the tagged-photon beam facility at the ELSA electron accelerator in Bonn. This experiment was part of a series of neutral meson production experiments on various targets. For this purpose, the Crystal Barrel and TAPS photon spectrometers have been combined to provide a 4pi detector for multi-neutral-particle final states. A high-quality excitation function, recoil polarizations, and angular diestributions from threshold up to 2.3 GeV center-of-mass energy were obtained. The results are compared with predictions of recent coupled-channel calculations within the K-matrix formalism and are interpreted by the partial-wave analysis within the Bonn-Gatchina model.
