Observation of CP violation in $D^0\to K^{-}{\pi }^{+}$ as a smoking gun for New Physics

David Delepine, Gaber Faisel, Carlos A. Ramirez

In this paper, we study the Cabibbo favored non-leptonic $D^0$ decays into $K^{-}{\pi }^{+}$ decays. First we show that, within the Standard Model, the corresponding CP asymmetry is strong…
