We calculate the direct CP violating asymmetry for B --> p p p and B --> p p K decays, in the case where rw mixing effects are taken into account. We find that the direct CP asymmetry reaches its maximum when the invariant mass p p is in the vicinity of the w meson mass. Moreover, the inclusion of rw mixing provides an opportunity to erase, without ambiguity, the phase uncertainty mod(p) in the determination of the CKM angles a in case of b --> u and g in case of b --> s.
