Zusammenfassung: | Since the discovery of the $\Lambda(1405)$, it remains poorly described by
conventional constituent quark models, and it is a candidate for having an
"exotic" meson-baryon or "penta-quark" structure, similar to states recently
reported in the hidden charm sector.
The $\Lambda(1405)$ can be produced in the reaction $\gamma p \rightarrow
K^+\Lambda(1405)$. The pure I=0 decay mode into $\Sigma^0\pi^0$ is prohibited
for the mass-overlapping $\Sigma(1385)$. Combining a large aperture forward
magnetic spectrometer and a central BGO crystal calorimeter, the BGO-OD
experiment is ideally suited to measure this decay with the $K^+$ in the
forward direction. Preliminary results are presented.
