    Abstract: We report the results of a search for the rare baryonic decays B0→pp¯, ΛΛ¯, and B+→pΛ¯. The analysis is based on a data set of 31.7×106BB¯ 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→pp¯)<1.2×10−6, B(B0→ΛΛ¯)<1.0×10−6, and B(B+→pΛ¯)<2.2×10−6 at the 90% confidence level.
