AbstractWe introduce a set of observables representing angular distribution asymmetries, which can be viewed as a generalization of the forward-backward asymmetry of angular distributions, and can be used as an effective tool to search for $$C\!P$$ C P violation in three-body decays of bottom and charmed baryons. We propose to search for such $$C\!P$$ C P asymmetries (1) in decays with $$\Lambda ^0$$ Λ 0 , $$\Sigma ^\pm $$ Σ ± , or $$\Lambda _c^+$$ Λ c + involved, such as $$\Lambda _b\rightarrow \Lamb...
