Abstract

Using 29.1 fb -1 of data accumulated at the γ(4S) with the Belle detector at KEKB, we have studied the decay modes B̄ 0→Λ c +p̄π + π -→ B -→Λ c +p̄π -, and B̄ 0→Λ c +p̄. We report branching fractions of exclusive B decays to charmed baryons with four-, three- and two-body final states, including intermediate ∑ c ++ and ∑ c 0 states. We observed B̄ 0→∑ c2(2455) ++p̄π - for the first time with a branching fraction of (2.38 -0.55 +0.63±0.41 ±0.62)×10 -4 and observed evidence for the two-body decay B -→∑ c(2455) 0p̄ with a branching fraction of (0.45 -0.19 +0.26±0.07±0.12) ×10 -4. We also set improved upper limits for the two-body decays B̄ 0→Λ c +p̄ and B̄ -→∑ c(2520) 0p̄.
