摘要We report the measurement of the charmed baryonic decay (B) over bar (0) --> Lambda(c)(+) (p) over bar with a branching fraction of (2.19(-0.49)(+0.56) +/- 0.32 +/- 0.57) x 10(-5) and a statistical significance of 5.8 sigma. The errors are statistical, systematic, and the error of the Lambda(c)(+) --> pK(-)pi(+) decay branching fraction. This is the first observation of a two-body baryonic B decay. The analysis is based on 78.2 fb(-1) of data accumulated at the Y(4S) resonance with the Belle detector at the KEKB asymmetric e(+)e(-) collider.
