C P violation in baryon decay processes is still undiscovered to date. We present a general analysis of the decay-angular-distributions and the corresponding C P asymmetries in cascade decays of the type ℍ→ R(→ ab) c, where ℍ is a heavy hadron that decays through weak interactions ℍ→ R c, and the resonance R decays strongly via R→ ab. Based on the analysis, we propose to search for C P violation in the decay-angular-distributions in the cascade decay processes \mathbbB→ B M, with B or M subsequently decaying through strong interactions, where \mathbbB is the mother baryon, B or M are the daughter baryon and meson, respectively, and M has to be spin-nonzero. We also present some typical decay channels in which the search for such kinds of C P asymmetries can be performed.
