Charm mixing at LHCb
We report a measurement of the time-dependent ration of $D^0 \to K^{+} \pi^{-}$ to $D^0 \to K^{-}\pi^{+}$ decay rates in $D^{*+}$-tagged events using 1.0 fb$^{-1}$ of integrated luminosity recorded by the LHCb experiment. We measure the mixing parameters $x'^2$ = (-0.9 $\pm$ 1.3) x 10$^{-4}, y&...
