Direct CP violation in $B^{\pm }\to p\bar{p}{K}^{(\ast )\pm }$

Abstract

We study the direct CP violation in $B^{\pm }\to p\bar{p}{K}^{(\ast )\pm }$ decays in the standard model. We point out that these three-body baryonic B decays can be important tools for detecting the direct CP violation in the charged $B$ system, in which there are no conclusive signatures yet. In particular, we show that the direct CP violating asymmetry in $B^{\pm }\to p\bar{p}{K}^{\ast \pm }$ is around 22% which supports the recent data by the BABAR Collaboration.
