This data sample was recorded with the BABAR detector at the PEP-II storage ring at SLAC. We find B(B¯0→Λ+cp¯K−K+)=(2.5±0.4(stat)±0.2(syst)±0.6B(Λ+c))×10−5, where the uncertainties are statistical, systematic, and due to the uncertainty of the Λ+c→pK−π+ branching fraction, respectively. The result has a significance corresponding to 5.0 standard deviations, including all uncertainties. For the resonant decay B¯0→Λ+cp¯ϕ, we determine the upper limit B(B¯0→Λ+cp¯ϕ)<1.2×10−5 at 90% confidence level. |
