Abstract
We first review direct CP violation in the three-body baryonic (Formula presented.) decays of (Formula presented.) with (Formula presented.) and (Formula presented.). We then present our recent results of the direct CP violating asymmetries in the two-body (Formula presented.) decays of (Formula presented.) as well as the three-body (Formula presented.). In particular, we emphasize that the large direct CP violating asymmetries in (Formula presented.) and (Formula presented.) are both around 20%, which are accessible to the b-hadron experiments.
