LHCb - Charm mixing in D0 → K±π∓π±π∓

Measurements of the charm-meson mixing and CP-violation parameters are important tests of the Standard Model and any deviations observed could hint at New Physics. A measurement of the time-dependent ratio of $D^0 \rightarrow K^+ \pi^- \pi^+ \pi^-$ to $D^0 \rightarrow K^- \pi^+ \pi^- \pi^+$ decays using prompt LHCb data would improve the precision on these observables. Moreover, knowledge can be gained about the hadronic parameters that describe the $D^0 \rightarrow K^\pm \pi^\mp \pi^\pm \pi^\mp$ decays, which are important inputs in a measurement of the CKM angle using $B \rightarrow D K, D^0 \rightarrow K^\pm \pi^\mp \pi^\pm \pi^\mp$ decays. This poster presents the methodology of the study, and the expected sensitivity to the parameters of interest.
