Abstract

Using data samples of eþe− collisions collected at the ϒð1SÞ, ϒð2SÞ, and ϒð3SÞ resonances with the Belle detector, we search for the three-body decay of the Ωð2012Þ baryon to KπΞ. This decay is predicted to dominate for models describing the Ωð2012Þ as a KΞð1530Þ molecule. No significant Ωð2012Þ signals are observed in the studied channels, and 90% credibility level upper limits on the ratios of the branching fractions relative to KΞ decay modes are obtained.
