Study of $B^{-} \rightarrow \Lambda_{c}^{+} \bar{p} \pi^{-}$ at BaBar

We present a branching fraction measurement for the decay $B^{- } \rightarrow \Lambda_{c}^{+} \bar{p} \pi^{-}$ using data from 232 million $B\bar{B}$ pairs collected at the BaBar detector at the Stanford Linear Accelerator Center. We compare this branching fraction measurement to the branching fraction of the two-body mode $\bar{B^{0}} \rightarrow \Lambda_{c}^{+} \bar{p} $. This comparison can yield insight into the dynamics of baryon production. We also study the resonant substructure of the three-body decay.
