Measurement of Baryonic B Decays

Abstract

Recent results of baryonic B decays from Belle are reported. This study is done by a 78 fb$^{-1}$ data sample, consisting of $85.0 \pm 0.5$ million $B\bar{B}$ pairs, collected by the Belle detector at the KEKB asymmetric energy $e^+e^-$ (3.5 on 8 GeV) collider. The results reported here include the first observation of the two-body decay $B^0 \to p\barΛ_c$, the first hyperonic decay $B^0 \to p\barΛπ^-$, and first observations of $B^+ \to p\bar{p}π^+$, $B^0 \to p\bar{p}K_S^0$, and $B^+ \to p\bar{p}K^{\star +}$.
