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. © 2005 The American Physical Society.
