We study the angular distributions of the baryon-antibaryon low-mass enhancements in the three-body baryonic $B$ decays of $B\ensuremath{\rightarrow}p\overline{p}M$ ($M=K$ and $\ensuremath{\pi}$) in the framework of the perturbative QCD. By writing the most general forms for the transition form factors of $B\ensuremath{\rightarrow}p\overline{p}$, we find that the angular distribution asymmetry in ${B}^{\ensuremath{-}}\ensuremath{\rightarrow}p\overline{p}{K}^{\ensuremath{-}}$ …
