Abstract

We search for CP violation in a sample of 20 000 Cabibbo-suppressed decays, D+→K+KS0π+π-, and 30 000 Cabibbo-favored decays, Ds+→K+KS0π+π-. We use 520 fb-1 of data recorded by the BABAR detector at the PEP-II asymmetric-energy e+e- collider operating at center of mass energies near 10.6 GeV. We search for CP violation in the difference between the T-odd asymmetries obtained using triple product correlations of the D+ (Ds+) and D- (Ds-) decays, respectively. The T violation parameter values obtained are AT(D+)=(-12.0±10.0stat±4.6syst)×10-3 and AT(Ds+)=(-13.6±7.7stat±3.4syst)×10-3, which are consistent with the standard model expectations.
