Abstract
We report the observation of the baryonic decay using a data sample of pairs produced in annihilations at . This data sample was recorded with the BABAR detector at the PEP-II storage ring at SLAC. We find , where the uncertainties are statistical, systematic, and due to the uncertainty of the branching fraction, respectively. The result has a significance corresponding to 5.0 standard deviations, including all uncertainties. For the resonant decay , we determine the upper limit at 90% confidence level.
