We reconstruct ${B}^{\ifmmode\pm\else\textpm\fi{}}\ensuremath{\rightarrow}D{K}^{\ifmmode\pm\else\textpm\fi{}}$ decays in a data sample collected by the CDF II detector at the Tevatron collider corresponding to $1\text{ }\text{ }{\mathrm{fb}}^{\ensuremath{-}1}$ of integrated luminosity. We select decay modes where the $D$ meson decays to either ${K}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$ (flavor eigenstate) or ${K}^{\ensuremath{-}}{K}^{+}$, ${\ensuremath{\pi}}^{\ensuremath{-}}{\ensuremath{\pi}}^{+}$ ($CP$-even eigenstates), and measure the direct $CP$ …
