摘要：In the QCD factorization (QCDF) approach we study the direct CP violation in via the mixing mechanism. We find that the CP violation can be enhanced by double mixing when the masses of the pairs are in the vicinity of the resonance, and the maximum CP violation can reach 28%. We also compare the results from the naive factorization and the QCD factorization.
