Probing CP Violation in Omega->Lambda K->p pi K Decay
Jusak Tandean
Abstract
The sum of the CP-violating asymmetries AOmega and ALambda in the decay sequence Omega->Lambda K, Lambda->p pi is presently being measured by the E871 experiment. We evaluate contributions to AOmega from the standard model and from possible new physics, and find them to be smaller than the corresponding contributions to ALambda, 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.
