Abstract

We study the direct CP violation in B±ppˉK()±B^\pm\to p\bar p K^{(*)\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 BB system, in which there are no conclusive signatures yet. In particular, we show that the direct CP violating asymmetry in B±ppˉK±B^\pm\to p\bar p K^{*\pm} is around 22% which supports the recent data by the BABAR Collaboration.
