Search for $B$ Meson Decays to Two Charm Baryons

We present measurements of the branching ratios of $B$ decays to charm baryon pairs in the reactions $\bar{B} \rightarrow\Lambda_c\:\overline{\Lambda_c}\:K$ and $\bar{B}\rightarrow\Xi_c\:\overline{\Lambda_c}$. The analysis is based on a $210\,{\rm fb}^{-1}$ data sample collected by the BaBar detector at the PEP-II $e^+e^-$ storage rings at SLAC.
