| 英文摘要 | The B -> K(*)rho, K(*)omega decays are useful to determine the Cabbibo-Kobayashi-Maskawa (CKM) angle phi(3) = gamma. Their polarization fractions are also interesting because of the polarization puzzle of the B -> phi K-* decay. We study these decays in the perturbative QCD approach based on k(T) factorization. After calculating the nonfactorizable and annihilation type contributions, in addition to the conventional factorizable contributions, we find that the contributions from the annihilation diagrams are crucial. They give dominant contribution to the strong phases and suppress the longitudinal polarizations. Our results agree with the current existing data. We also predict sizable direct CP asymmetries in B+ -> K(*+)rho(0), B-0 -> K(*+)rho(-), and B+ -> K(*+)omega decays, which can be tested by the oncoming measurements in the B factory experiments. |
