Updated determination of $D^0$-$\overline{D}{}^0$ mixing and CP violation parameters with $D^0\to K^{+}{\pi }^{-}$ decays

LHCb collaboration, R. Aaij, B. Adeva +792

We report measurements of charm-mixing parameters based on the decay-time-dependent ratio of $D^0\to K^{+}{\pi }^{-}$ to $D^0\to K^{-}{\pi }^{+}$ rates. The analysis uses a data sample of proton-pro…
