  "abstract": "We report the results of a search for the rare baryonic decays $B^0 \\to p\\bar{p}$, $\\Lambda\\bar{\\Lambda}$, and $B^+ \\to p\\bar{\\Lambda}$. The analysis is based on a data set of $31.7\\times 10^6 B\\bar{B}$ 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 ${\\mathcal B}(B^0 \\to p\\bar{p}) < 1.2 \\times 10^{-6}$, ${\\mathcal B}(B^0 \\to \\Lambda\\bar{\\Lambda}) < 1.0 \\times 10^{-6}$, and ${\\mathcal B}(B^+ \\to p\\bar{\\Lambda}) < 2.2 \\times 10^{-6}$ at the 90% confidence level.",
