Physical Review D

Using data samples of e(+)e(-) collisions collected at the Upsilon(1S), Upsilon(2S), and Upsilon(3S) resonances with the Belle detector, we search for the three-body decay of the Omega(2012) baryon to K pi Xi. This decay is predicted to dominate for models describing the Omega(2012) as a K Xi(1530) molecule. No significant Omega(2012) signals are observed in the studied channels, and 90% credibility level upper limits on the ratios of the branching fractions relative to K Xi decay modes are obtained.
