Abstract
We report the observation of the baryonic -decay , excluding contributions from the decay . Using a data sample of pairs collected with the BABAR detector at the PEP-II storage ring at SLAC, the measured branching fraction is . In addition we find evidence for the resonant decay and determine its branching fraction to be . The errors are statistical, systematic, and due to the uncertainty in the branching fraction. For the resonant decay we obtain an upper limit of at 90% confidence level.
