Abstract

An attempt was made to search for direct charge-conjugation/parity (CP) violation in nonleptonic decays of charged Ξ and Λ by determining the asymmetry parameter A_ΞΛ. Results obtained in this study were found to be consistent with no CP violation at the 10^-2 level in the nonleptonic decays of charged Ξ and Λ.
