Measuring $D^0-{\bar{D}}^0$ Mixing and Relative Strong Phases at a Charm Factory

Abstract

We propose a set of measurements at a charm factory to determine the $D^0-{\bar{D}}^0$ mixing parameters $\Delta M$ and $\Delta \Gamma$ and the strong phase difference $\delta$ between doubly-Cabibbo-suppressed (DCS) and Cabibbo-favored (CF) neutral $D$ decays into $K^{-}{\pi }^{+}$. 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 $D^0$--${\bar{D}}^0$ mixing.
