Photoproduction of Σ+ K0 off the proton with the CBELSA/TAPS experiment — •Nicolas Kolanus for the CBELSA/TAPS collaboration — Helmholtz-Institut für Strahlen- und Kernphysik, Universität Bonn, Nussallee 14-16, 53115 Bonn
The CBELSA/TAPS experiment is especially well suited to measure photons from neutral meson decays to study N*- and Δ*-resonances which are created via photoproduction. By looking at triple neutral pion photoproduction it is also possible to investigate the kaon-hyperon final state, Σ+ K0. Data in the strange sector is of specific interest not only to investigate strange decays of non-strange baryons but also for coupled-channel partial wave analyses used to extract the resonances from the data.
Investigating the photoproduction of Σ+ K0 poses some challenges since its cross section is significantly lower than the cross section for many non-strange final states while the number of particles to be measured is relatively high. As the particles containing strangeness are detected in the p3π0-final state, the signal of interest needs to be carefully separated from the background of other triple neutral pion events.
This talk will focus on the selection of γ p → Σ+ K0 → p 3π0 events and discuss preliminary results on the differential cross section as well as on polarisation observables.
