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