Charm mixing at LHCb
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 $x'^2=(-0.9\pm1.3)\times10^{-4}$, $y'=(7.2\pm2...
