Measurement of mixing and CP violation parameters in two-body charm decays

Abstract:

A study of mixing and indirect CP violation in D 0 mesons through the determination of the parameters y CP and A Γ is presented. The parameter y CP is the deviation from unity of the ratio of effective lifetimes measured in D 0 decays to the CP eigenstate K +K - with respect to decays to the Cabibbo favoured mode K -π +. The result measured using data collected by LHCb in 2010, corresponding to an integrated luminosity of 29 pb -1, is yCP = (5.5 ± 6.3 stat ± 4.1 syst) × 10 -3. The parameter A...
