Abstract
We report the observation of the decay mode based on an analysis of of data collected by the Belle detector at KEKB. This is the first example of a transition with baryons in the final state. The mass spectrum in this decay is inconsistent with phase space and is peaked at low mass. The branching fraction for this decay is measured to be . We also report upper limits for the decays and .
