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.
