摘要Systematically, we study the long-range contribution to the mixing effects based on the potential model while the QCD correction in Hamiltonian being taken into account. We have found that the long-distance effects are important to K0-K0BAR and D0-D0BAR, but B0-B0BAR. The QCD correction causes a change to the results, enhances the mixing, for K0-K0BAR, by a factor of 1.3, whereas for D0-D0BAR it is a suppression of about 0.7. The absorptive parts which give rise to DELTA-GAMMA have also been discussed and the diquark-intermediate-state contributions to D and B systems are included.
