Using data from the FOCUS (E831) experiment, we have searched for T violation in charm meson decays using the four-body decay channels D-0 -> K(-)K(+)pi(-)pi(+), D+ -> K(S)(0)K(+)pi(-)pi(+), and D-s(+) -> K(S)(0)K(+)pi(-)pi(+). The T violation asymmetry is obtained using triple-product correlations and assuming the validity of the CPT theorem. We find the asymmetry values to be A(Tviol)(D-0) = 0.010 +/- 0.057(stat.) +/- 0.037(syst.), A(Tviol)(D+) = 0.023 +/- 0.062(stat.) +/- 0.022(syst.), and A(Tviol)(D-s(+)) = -0.036 +/- 0.067(stat.) +/- 0.023(syst.). Each measurement is consistent with no T violation. New measurements of the CP asymmetries for some of these decay modes are also presented. (c) 2005 Elsevier B.V. All rights reserved.
