Mixing and CP violation in D-0 -> K-pi(+) decays

Abstract:

We review the experimental methods to measure mixing and time-dependent CP violation in D0 decays into two hadrons. While these phenomena are usually neglected for D0 → K−π+ decays, this approximation is not always justified. In particular, it produces a bias on the measurement of the parameter yCP, when this is performed by relying on D0 → K−π+ decays as a normalisation channel, whose size is around 40% of the precision of the current world average. Finally, we estimate the sensitivity to th...
