Available in PDF, EPUB and Kindle. Book excerpt: Using 385 fb−1 of ee− collision data collected at center-of-mass energies around 10.6 GeV, we search for time-integrated CP violation in the Cabibbo-suppressed decays D°/{bar D}° →?−?+?° and D°/{bar D}° → K−K+?° 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.
