Abstract

We report the observation of B-→J/ψΛp̄ and searches for B-→J/ψΣ0p̄ and B0→J/ψpp̄ decays, using a sample of 275×106 BB̄ pairs collected with the Belle detector at the Υ(4S) resonance. We observe a signal of 17.2±4.1 events with a significance of 11.1σ and obtain a branching fraction of B(B-→J/ψΛp̄)=11.6±2.8(stat)-2.3+1.8(sys)×10-6. No signal is found for either of the two decay modes, B-→J/ ψΣ0p̄ and B0→J/ψpp̄, and upper limits for the branching fractions are determined to be B(B-→J/ψΣ0p̄)<1. 1×10-5 and B(B0→J/ψpp̄)<8.3×10-7 at 90% confidence level.

Funding Information:
The REWIND trial was sponsored and funded by Eli Lilly and Company and led by an international steering committee that was coordinated by the Population Health Research Institute (Hamilton, ON, Canada), which also analysed the data for this report after the database was locked. ICON Clinical Research managed study sites and obtained data. Scientists employed by the funder were on the REWIND steering committee and contributed to trial design, trial implementation, and data interpretation. All authors and the sponsor jointly made the decision to submit for publication. The corresponding author had full access to all data in the study and had final responsibility for the decision to submit for publication.
