| description | We report a search for CP violation in the decay modes D[superscript ±]→K[subscript S][superscript 0]K[superscript ±], D[subscript s][superscript ±]→K[subscript S][superscript 0]K[superscript ±], and D[subscript s][superscript ±]→K[subscript S][superscript 0]π[superscript ±] using a data set corresponding to an integrated luminosity of 469 fb[superscript -1] collected with the BABAR detector at the PEP-II asymmetric energy e[superscript+]e[superscript -] storage rings. The decay rate CP asymmetries, A[subscript CP], 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[superscript ±]→K[subscript S][superscript 0]K[superscript ±] and D[subscript s][superscript ±]→K[subscript S][superscript 0]K[superscript ±] modes, and (+0.332±0.006)% for the D[subscript s][superscript ±]→K[subscript S][superscript 0]π[superscript ±] mode]. They are the most precise determinations to date. |
