摘要：

Due to the presence of quantum correlations in the C=-1 and C=+1 D-0(D) over bar (0) pairs produced in the reactions e(+)e(-)-> D-0(D) over bar (0)(n pi(0)) and e(+)e(-)-> D-0(D) over bar (0)gamma(n pi(0)), respectively, the time-integrated D-0(D) over bar (0) 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 D-0-(D) over bar (0) mixing. We present a method for simultaneously measuring the magnitudes and phases of these amplitude ratios and searching for D-0-(D) over bar (0) mixing. We make use of fully- and partially-reconstructed D-0(D) over bar (0) 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 K-0(K) over bar (0), B-0(B) over bar (0), or B-s(0)(B) over bar (0)(s) pairs.
