Model-independent D⁰-D⁰ mixing and CP violation studies with D⁰ → K⁰ Sπ+π- and D⁰ → K⁰ SK+K-

Original · EN

Simulation studies are performed to assess the sensitivity of a model-independent analysis of the flavour-tagged decays D⁰ → K⁰ Sπ+π- and D⁰ → K⁰ SK+K- to mixing and CP violation. The analysis takes as input measurements of the D decay strong-phase parameters that are accessible in quantum-correlated D-D pairs produced at the ψ(3770) resonance. It is shown that the model-independent approach is well suited to the very large data sets expected at an upgraded LHCb experiment, or future high luminosity e+e- facility, and that with 100M K⁰ Sπ+π- decays a statistical precision of around 0.01 and 0.7∘ is achievable on the CP violation parameters rCP and aCP, respectively. Even with this very large sample the systematic uncertainties associated with the strong-phase parameters will not be limiting, assuming that full use is made of the available ψ(3770) data sets of CLEO-c and BES-III. Furthermore, it is demonstrated that large flavour-tagged samples can themselves be exploited to provide information on the strong-phase parameters, a feature that will be beneficial in the measurement of the CKM angle γ/ϕ₃ with B- → DK- decays.
