Charm Physics at LHCb
Dr. Marco Gersabeck (CERN)


LHCb has completed its first year of data taking at the LHC.
The prolific production of open charm at \(\sqrt{s}=7~\mathrm{TeV}\) already allows precision measurements to be made.
The sector of open charm measurements will be introduced with particular emphasize on measurements of mixing and CP violation.
The status and first results of measurements of mixing and CP violation using two-body final states will be reviewed in detail.

Measurements of mixing and indirect CP violation via the parameters \(y_{CP}\) and \(A_\Gamma\) using time-dependent studies of singly Cabibbo suppressed decays will be discussed.
Particularly, a technique for handling biases of the lifetime distribution in a simulation-free manner is 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 yields \(A_{CP}(KK)-A_{CP}(\pi\pi)=(-0.28\pm0.70_{stat}\pm0.25_{syst})%\).
An outlook will cover the perspectives of charm physics at LHCb for the ongoing LHC running period.
