Abstract
Heavy meson pairs produced in the decays of heavy quarkonium resonances at machines (beauty and tau-charm factories) have the useful property that the two mesons are in the -correlated states. We show that this leads to time-independent correlations allowing the extraction of the lifetime difference and other mixing parameters. In particular, for the decay the correlation of a flavor specific decay of one with a -specific decay of the other is linearly sensitive to the lifetime difference. The utility of this method is considered at CLEO-c as well as future threshold charm factories. We include the impact of possible -violating effects and present the complete results for time-integrated -entangled decay rates with violation taken into account. We comment on the utility of using this method to extract the lifetime difference of neutral mesons at future high luminosity factories.
