We report a search for CP violation in the decay modes D-+/- -> (KSK +/-)-K-0, D-s(+/-) -> (KSK +/-)-K-0, and D-s(+/-) -> K-S(0)pi(+/-) using a data set corresponding to an integrated luminosity of 469 fb(-1) collected with the BABAR detector at the PEP-II asymmetric energy e(+)e(-) storage rings. The decay rate CP asymmetries, ACP, are determined to be (+0.13 +/- 0.36(stat) +/- 0.25(syst))%, (-0.05 +/- 0.23(stat) +/- 0.24(syst))%, and (+0.6 +/- 2.0(stat) +/- 0.3(syst))%, respectively. These measurements are consistent with zero, and also with the Standard Model prediction [(-0.332 +/- 0.006)% for the D-+/- -> (KSK +/-)-K-0 and D-s(+/-) -> (KSK +/-)-K-0 modes, and (+0.332 +/- 0.006)% for the D-s(+/-) -> K-S(0)pi(+/-) mode]. They are the most precise determinations to date. | |||
