Abstract

We report the results of a search for the rare baryonic decays B⁰→pp̄, ΛΛ, and B⁺→pΛ. The analysis is based on a data set of 31.7×10⁶ BB̄ events collected by the Belle detector at the KEKB e⁺e^- collider. No statistically significant signals are found, and we set branching fraction upper limits B(B⁰→pp̄)<1.2×10^-6, B(B⁰→ΛΛ)<1.0×10⁶, and B(B⁺→pΛ)<2.2×10^-6 at the confidence level.
