Description
Due to the presence of quantum correlations in the C=-1 and C=+1 D0D0 pairs produced in the reactions e+e-→D0D0(nπ0) and e+e-→D0D0γ(nπ0), respectively, the time-integrated D0D0 decay rates are sensitive to interference between amplitudes for indistinguishable final states. The size of this interference is governed by the relevant amplitude ratios and can include contributions from D0-D0 mixing. We present a method for simultaneously measuring the magnitudes and phases of these amplitude ratios and searching for D0-D0 mixing. We make use of fully- and partially-reconstructed D0D0 pairs in both C eigenstates, and we estimate experimental sensitivities based on a plausible charm factory data set. Similar analyses can be applied to coherent K0K0, B0B0, or Bs0Bs0 pairs
