The sum of the CP-violating asymmetries A_Omega and A_Lambda in the decaysequence Omega->Lambda K, Lambda->p pi is presently being measured by the E871experiment. We evaluate contributions to A_Omega from the standard model andfrom possible new physics, and find them to be smaller than the correspondingcontributions to A_Lambda, although not negligibly so. We also show that thepartial-rate asymmetry in Omega->Lambda K is nonvanishing due to final-stateinteractions. Taking into account constraints from kaon data, we discuss howthe upcoming result of E871 and future measurements may probe the variouscontributions to the observables.Comment: 19 pages, 4 figure
