  "abstract": "We report results of a search for the charmless two-body baryonic decays B^0 \\to p \\bar{p}, B^0 \\to \\Lambda \\bar{\\Lambda}, and B^+\\to p \\bar{\\Lambda} based on the analysis of a 140 fb^{-1} data sample. We set 90% confidence level upper limits on their branching fractions: B(B^0 \\to p \\bar{p}) < 4.1 x 10^{-7}, B(B^0 \\to \\Lambda \\bar{\\Lambda}) < 6.9 x 10^{-7}$, and B(B^+ \\to p \\bar{\\Lambda}) < 4.9 x 10^{-7}.",
