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.
