EnglishAbstract
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 -> 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
