Measurement of $CP$ asymmetry in $D^0\to K^{-}{K}^{+}$ and $D^0\to {\pi }^{-}{\pi }^{+}$ decays

LHCb collaboration, R. Aaij, B. Adeva +697

Time-integrated $CP$ asymmetries in $D^0$ decays to the final states $K^{-}{K}^{+}$ and ${\pi }^{-}{\pi }^{+}$ are measured using proton-proton collisions corresponding to $3{\mathrm{fb}}^{-1}$ of i…
