Triple product asymmmetries in Λ_b and Xi_b decays

The LHCb experiment is capable of studying four-body decays of the $b$-flavored baryons $\Lambda_b$ and $\Xi_b^0$ to charmless final states consisting of charged pions, kaons, and baryons. We remark on the search in such modes for CP-violating triple product asymmetries and for CP rate asymmetries relative to decays involving charmed baryons.
