Analysis of the reaction γ p→ K⁰ Σ⁺ in the neutral decay channel at the BGO-OD experiment using kinematic fitting — •Stefan Alef for the BGO-OD collaboration — Physikalisches Institut Universität Bonn

The BGO-OD experiment at the ELSA facility in Bonn is built to investigate nucleon excitations via meson photoproduction. One research objective is associated strangeness production, which includes the reaction channel γ p→ K⁰ Σ⁺.

Results of the analysis for the neutral decay channel K⁰ Σ⁺→ π⁰π⁰π⁰ p will be presented. Due to the small production cross section and branching ratio kinematic fitting is used to discriminate the reaction against background.
