Abstract
Since the discovery of the , 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 can be produced in the reaction . The pure I=0 decay mode into is prohibited for the mass-overlapping . 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 in the forward direction. Preliminary results are presented. *Supported by DFG (PN 388979758, 405882627).
