Measuring D0–D̄0 mixing and relative strong phases at a charm factory

We propose a set of measurements at a charm factory to determine the D0–D̄ 0 mixing parameters ΔM and ΔΓ and the strong phase difference δ between doubly-Cabibbo-suppressed (DCS) and Cabibbo-favored (CF) neutral D decays into K−π+. The method can also be used to measure strong phase differences between other corresponding DCS and CF amplitudes. These phase differences are important for studies of D0–D̄ 0 mixing.
