Abstract
The sum of the CP-violating asymmetries A_Omega and A_Lambda in the decay sequence Omega->Lambda K, Lambda->p pi is presently being measured by the E871 experiment. We evaluate contributions to A_Omega from the standard model and from possible new physics, and find them to be smaller than the corresponding contributions to A_Lambda, although not negligibly so. We also show that the partial-rate asymmetry in Omega->Lambda K is nonvanishing due to final-state interactions. Taking into account constraints from kaon data, we discuss how the upcoming result of E871 and future measurements may probe the various contributions to the observables.
