    • Abstract:Direct CP violation in the hadronic charm decays provides a good testing ground for the Kobayashi-Maskawa mechanism in the Standard Model. Any significant deviations from the expectation would be indirect evidence of physics beyond the Standard Model. Recently, LHCb has announced the first observation of CP violation in the charm sector. It is most important to explore whether this observation of CP noninvariance is consistent with the standard model or not. We analyze D to PP and VP decays in the topological diagram approach. Our prediction for the CP asymmetry difference between K+K- and pi+pi- modes is consistent with the latest data. Moreover, we suggest an attractive and measurable observable in the VP sector.
