Search for CP violation in neutral D meson Cabibbo-suppressed three-body decays

Using 385fb-1 of e+e- collision data collected at center-of-mass energies around 10.6 GeV, we search for time-integrated CP violation in the Cabibbo-suppressed decays D0/D̄0→π-π+π0 and D0/D̄0→K-K+π0 with both model-independent and model-dependent methods. Measurements of the asymmetries in amplitude...

Description
Summary:Using 385fb-1 of e+e- collision data collected at center-of-mass energies around 10.6 GeV, we search for time-integrated CP violation in the Cabibbo-suppressed decays D0/D̄0→π-π+π0 and D0/D̄0→K-K+π0 with both model-independent and model-dependent methods. Measurements of the asymmetries in amplitudes of flavor states and CP eigenstates provide constraints on theories beyond the standard model, some of which predict CP violation in amplitudes at the 1% level or higher. We find no evidence of CP violation and hence no conflict with the standard model. © 2008 The American Physical Society.
