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…

We report an updated study of the suppressed decays $B^- \to [K^+\pi^-]_D K^-$ and $B^- \to [K^+\pi^-]_D \pi^-$ where $[K^+\pi^-]_D$ indicates that the $K^+\pi^-$ pair originates from a neutral $D$ meson. A data sample containing 386…
