D0-(D)over-bar0 mixing in Υ(1S)→D0(D)over-bar0 decay at a super-B factory

D-0-(D) over bar (0) mixing and significant CP violation in the charm system may indicate the signature of new physics. In this study, we suggest that the coherent D-0(D) over bar (0) events from the decay of Upsilon(1S)-> D-0(D) over bar (0) can be used to measure both mixing parameters and CP violation in charm decays. The neutral D mesons from Upsilon(1S) decay are strongly boosted, so that it will offer the possibility to measure the proper-time interval Delta t between the fully reconstructed D-0 and (D) over bar (0). Both coherent and time-dependent information can be used to extract D-0-(D) over bar (0) mixing parameters. The sensitivity of the measurement should be improved at B factories or at super-B.
