| dc.description | $\Dz-\Dzb$ mixing and significant CP violation in the charm system may indicate the signature of new physics. In this study, we suggest that the coherent $\DzDzb$ events from the decay of $Υ(1S) \to \Dz \Dzb$ can be used to measure both mixing parameters and CP violation in charm decays. The neutral $D$ mesons from $Υ(1S)$ decay are strongly boosted, so that it will offer the possibility to measure the proper-time interval, $Δt$, between the fully-reconstructed $\Dz$ and $\Dzb$. Both coherent and time-dependent information can be used to extract $\Dz-\Dzb$ mixing parameters. The sensitivity of the measurement should be improved at B factories or super-B. | |
