Abstract

We describe LHCb measurements for D⁰--D⁰ mixing parameters and searches for CP violation using "wrong-sign" D⁰→ K⁺π^- two-body decays. LHCb provides the world's most precise measurements of the mixing parameters to date, using 3 fb^-1 of pp collision data. By measuring the mixing parameters separately for D⁰ and D⁰, and allowing for CP violation, the LHCb results also place the world's most stringent constraints on the CP violation parameters, |q/p| and A_D, from a single experiment.
