Abstract

We report results of a search for CP violation in the singly Cabibbo-suppressed decays D⁺ → K^- K⁺ π⁺, θπ⁺, K̄* (892)⁰K⁺, and π^- π⁺ π⁺ based on data from the charm hadroproduction experiment E791 at Fermilab. We search for a difference in the D⁺ and D^- decay rates for each of the final states. No evidence for a difference is seen. The decay rate asymmetry parameters (A_CP), defined as the difference in the D⁺ and D^- decay rates divided by the sum of the decay rates, are measured to be: A_CP(KKπ) = -0.014 ± 0.029, A_CP(θπ) = -0.028 ± 0.036, A_CP (K* (892) K) = -0.010 ± 0.050, and A_CP (πππ) = -0.017 ± 0.042.
