Abstract

We report the results of a search for CP-violating decay rate asymmetries (ACP) in the charm decay modes D+K-K+, D+K»*0K+, D++, and D0K+K-. Our measurements are all consistent with zero asymmetry: ACP=-0.0310.068, ACP(K*K)=-0.120.13, ACP()=0.0660.086, and ACP(KK)=0.0240.084. The data were accumulated by the Fermilab high energy photoproduction experiment E687.
