Abstract

We propose a set of measurements at a charm factory to determine the D⁰-D̄⁰ 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-D̄⁰ mixing.
