| 英文摘要 | We have analyzed the D -> pi K, K K decay with the naive factorization (NF), QCD factorization (QCDF) and QCD factorization including soft-gluon exchanges (QCDF + SGE). In these decay channels, the softgluon effects are firstly calculated with light cone QCD sum rules. Comparing the three kind approaches, we can find the calculation results have made Much more improved QCD factorization (QCDF) than the naive factorization (NF), and the calculation results have also made improved QCD factorization including soft-gluon exchanges (QCDF + SGE) than the QCD factorization (QCDF) in the color-suppressed decay channels. In addition, we find the soft-gluon effects are larger than the leading order contributions, and the calculation results are close to the experimental data for the color-suppressed decay channels. In color-allowed decay channel D-0 -> pi K-+(-), the soft-gluon effects are small and we should consider other power terms, such as final state interaction and annihilation effects.
