Study of (B)over-bar ->Xi(c)(Lambda)over-bar(c)(-) and (B)over-bar ->Lambda(+)(c)(Lambda)over-bar(c)(-)(K)over-bar decays at BABAR

Abstract:

We report measurements of B-meson decays into two- and three-body final states containing two charmed baryons using a sample of 230×106 Υ(4S)→BB̄ decays. We find significant signals in two modes, measuring branching fractions B(B-→Λc+Λ̄c-K-)=(1. 14±0.15±0.17±0.60)×10-3 and B(B- →Ξc0Λ̄c-)×B(Ξc0→Ξ-π+)=(2.08±0. 65±0.29±0.54)×10-5, where the uncertainties are statistical, systematic, and from the branching fraction B(Λc+→pK-π+), respectively. We also set upper limits at the 90% confidence level o...
