摘要：

We report results of a search for CP violation in the singly Cabibbo-suppressed decays D+ --> K(-)K(+)pi(+), phi pi(+), (K) over bar(892)K-0(+), and pi(-)pi(+)pi(+) 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 (ACP), 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)(KK pi) = -0.014+/-0.029, A(CP) (phi pi) = -0.028+/-0.036, A(CP) (K*(892)K) = -0.010+/-0.050, and A(CP)(7 pi pi pi) = -0.017+/-0.042.
