Description
The CBELSA/TAPS experiment is especially well suited to measure photons from neutral meson decays to study $N^*$- and $\Delta^∗$-resonances which are created via photoproduction off the nucleon. Investigating triple neutral pion photoproduction, the kaon-hyperon final state, $\Sigma^+K^0$, as well as the photoproduction of $\eta$ mesons decaying into 3$\pi^0$ can be studied.
The photoproduction of neutral kaons is of particular interest as the t-channel kaon exchange is suppressed which makes the channel more sensitive to resonant s-channel contributions. Data in the $\gamma p \to \Sigma^+K^0$ channel is, however, still scarce.
A challenge in the analysis presented, is the careful separation of the $\Sigma^+K^0 \to p3\pi^0$-signal from other triple neutral pion events not originating from kaon photoproduction.
This contribution in form of a poster will focus on the selection of $\gamma p \to p 3\pi^0$ events and discuss preliminary results in the $\Sigma^+K^0$ and $\eta$ photoproduction channels.
