| dc.description | We report the results of a search for the rare baryonic decays $B^0 \to p\bar{p}$, $Λ\barΛ$, and $B^+ \to p\barΛ$. 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 ${\mathcal B}(B^0 \to p\bar{p}) < 1.2 \times 10^{-6}$, ${\mathcal B}(B^0 \to Λ\barΛ) < 1.0 \times 10^{-6}$, and ${\mathcal B}(B^+ \to p\barΛ) < 2.2 \times 10^{-6}$ at the 90% confidence level. | |
