CP Violation and Mixing in Charm at LHCb

LHCb has completed its first year of data taking at the LHC. The prolific production of open charm at $\sqrt{s}$ = 7 Tev already allows precision measurements to be made.

Sumario:LHCb has completed its first year of data taking at the LHC. The prolific production of open charm at $\sqrt{s}$ = 7 Tev already allows precision measurements to be made. The prospects for time-dependent mixing and CP violation measurements, in particular y$_{CP}$ and A$_{\gamma}$ are discussed and results from preparatory studies are presented. First results on time-integrated CP violation measurements in two-body charm decays at LHCb are presented. The measurement of the CP violation difference in the channels $D^0 \to K^{+} K^{-}$ and $D^0 \to \pi^{+}\pi^{-}$ yields A$_{CP}(KK) - A_{CP}(\pi\pi)$ = (0.28$\pm$0.70$_{stat}\pm$0.25$_{syst})$%.
