Search for at Belle

Using data samples of collisions collected at the , , and resonances with the Belle detector, we search for the three-body decay of the baryon to . This decay is predicted to dominate for models describing the as a molecule. No significant signals are observed in the studied channels, and 90% credibility level upper limits on the ratios of the branching fractions relative to decay modes are obtained.
