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

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/189265We study the direct CP violation in $B^\pm\to p\bar p K^{(*)\pm}$ 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 $B$ system, in which there are no conclusive signatures yet. In particular, we show that the direct CP violating asymmetry in $B^\pm\to p\bar p K^{*\pm}$ is around 22% which supports the recent data by the BABAR Collaboration.7 pages, version to be published in Phys.
