Abstract

We report the results of a search for the rare baryonic decay modes B⁰→ΛΛ̄, B⁺→Λ̄p, B⁰→Λ̄pπ^-, and B⁰→pp̄ (and their charge conjugate states) using 5.8 × 10⁶ BB̄ pairs collected with the CLEO detector. We see no statistically significant signals in any of these modes and set 90% confidence level upper limits on their branching fractions, B(B⁰→ΛΛ̄)<3.9 × 10^-6, B(B⁺→Λ̄p)<2.6 × 10^-6, B(B⁰→Λ̄pπ^-)<1.3 × 10^-5 and B(B⁰→pp̄)<7.0 × 10^-6.
