Two-body wrong-sign mixing and CP violation

Abstract

We describe LHCb measurements for $D^0$--${\bar{D}}^0$ mixing parameters and searches for $CP$ violation using "wrong-sign" $D^0\to K^{+}{\pi }^{-}$ two-body decays. LHCb provides the world's most precise measurements of the mixing parameters to date, using 3 $f{b}^{-1}$ of $pp$ collision data. By measuring the mixing parameters separately for $D^0$ and ${\bar{D}}^0$, and allowing for $CP$ violation, the LHCb results also place the world's most stringent constraints on the $CP$ violation parameters, $|q/p|$ and $A_D$, from a single experiment.
