Observation of $D^0 - \overline{D}^0$ oscillations

We report a measurement of the time-dependent ratio 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'=(7.2 \pm 2...
