Measurements of B(B̄0→Λc+p̄) and B(B- →Λc+p̄π-) and studies of Λc+π- resonances

Measurements of B(B̄0→Λc+p̄) and B(B- →Λc+p̄π-) and studies of Λc+π- resonances

We present an investigation of the decays B̄0→Λc+p̄ and B-→Λc+p̄π- based on 383×106 Υ(4S) →BB̄ decays recorded with the BABAR detector. We measure the branching fractions of these decays; their ratio is B(B-→Λc+p̄π-)/ B(B̄0→Λc+p̄)=15.4±1.8±0.3. The B-→Λc+p̄π- process exhibits an enhancement at the Λ...
