Abstract

We report results of a search for the charmless two-body baryonic decays B⁰ → pp̄, B⁰ → ΛΛ̄, and B⁺ → pΛ̄ based on the analysis of a 140 fb ^-1 data sample. We set 90% confidence level upper limits on their branching fractions: B(B⁰ → pp̄) <4.1 × 10 ^-7, B(B⁰ → ΛΛ̄) <6.9 × 10^-7, and B(B⁺ → pΛ̄) <4.9 × 10^-7.
