Abstract
We report a search for the charmless baryonic decay with a data sample corresponding to an integrated luminosity of containing pairs. The data were collected by the Belle experiment running on the resonance at the KEKB collider. We measure a branching fraction , where the first uncertainty is statistical and the second is systematic. The signal has a significance of 3.1 standard deviations and constitutes the first evidence for this decay mode. We also search for the intermediate two-body decays and , and set an upper limit on the branching fraction, at 90% confidence level.
