Description

In a sample of 467 million BBbar pairs collected with the BaBar detector at the PEP-II collider at SLAC we have observed the decay B0bar->Λc+ pbar π0 and measured its branching fraction. We determine an upper limit for the branching fraction of the decay B0bar->Λc+(2455) pbar and observe an enhancement at the threshold of the invariant mass of the baryon-antibaryon pair. We also report the observation of the baryonic decay B0bar->Λc+ Λbar K-.
