KS0Σ0 photoproduction at the BGO-OD experiment — •Katrin Kohl for the BGO-OD collaboration — Physikalisches Institut, Nussallee 12, D-53115 Bonn
The BGO-OD experiment at the ELSA accelerator facility uses an energy tagged bremsstrahlung photon beam to investigate the exitation structure of the nucleon in meson photoproduction.
The associated photoproduction of KS0 and hyperons is essential to understand the role of K* exchange mechanisms. A cusp-like structure observed in the γ p → KS0Σ+ reaction at the K* threshold is described by models including dynamically generated resonances from vector meson-baryon interactions. Such interactions are predicted to give a peak like structure in KS0Σ0 photoproduction off the neutron.
This talk presents a preliminary analysis of the reaction γ n → KS0Σ0. First results seem to support the predicted peak like structure.
