Search for \bar{B}^0\toΛ_c^+\barΛ_c^- decay at Belle

The Belle Collaboration, K. Abe

We search for the doubly charmed baryonic decay ${\bar{B}}^0\to {\Lambda }_c^{+}{\bar{\Lambda }}_c^{-}$, in a data sample of $520\times 10^6$ $B\bar{B}$ events accumulated at the ${\rm Y}(4S)$ resonance with the B…
