| 英文摘要 | In this paper, we perform a global analysis of B-->PP and PV decays with the QCD factorization approach. It is encouraging to observe that the predictions of QCD factorization are in good agreement with experiment. The best fit gamma is around 79 degrees. The penguin-diagram-to-tree-diagram ratio \P-pipi/T-pipi\ of pi(+)pi(-) decays is preferred to be larger than 0.3. We also show the confidence levels for some interesting channels: B-0-->pi(0)pi(0), K+K-, and B+-->omegapi(+), omegaK(+). For B-->piK(*) decays, they are expected to have smaller branching ratios with more precise measurements. |
