Abstract: Using 385     fb − 1 of e + e − collision data collected at center-of-mass energies around 10.6 GeV, we search for time-integrated C P violation in the Cabibbo-suppressed decays D 0 / ¯¯¯ D 0 → π − π + π 0 and D 0 / ¯¯¯ D 0 → K − K + π 0 with both model-independent and model-dependent methods. Measurements of the asymmetries in amplitudes of flavor states and C P eigenstates provide constraints on theories beyond the standard model, some of which predict C P violation in amplitudes at the 1% level or higher. We find no evidence of C P violation and hence no conflict with the standard model.
