Abstract
We report the measurement of the charmed baryonic decay with a branching fraction of and a statistical significance of . The errors are statistical, systematic, and the error of the decay branching fraction. This is the first observation of a two-body baryonic decay. The analysis is based on of data accumulated at the resonance with the Belle detector at the KEKB asymmetric collider.
