| 内容記述 | We search for the doubly charmed baryonic decay \bar{B}^0 →Λ_c^+\bar{Λ}_c^-, in a data sample of 520×106 B\bar{B} events accumulated at the Υ(4S) resonance with the Belle detector at the KEKB asymmetric-energy e^+e^- collider. We find no significant signal and set an upper limit of B(\bar{B}^0 →Λ_c^+\bar{Λ}_c^-)< 6.2×10^{-5} at 90% confidence level. The result is significantly below a naive extrapolation from B(B^-→ Ξ\begin0\c\end\bar{Λ}_c^-) assuming a simple Cabibbo-suppression factor of |V_cd/V_cs|^2. The small branching fraction may be attributed to a suppression due to the large momentum of the baryonic decay products, which has been observed in other charmed baryonic two-body B decays. | |||||
