3 Abstract
v
0 The B → K ∗ρ, K ∗ω decays are useful to determine the CKM angle φ3 = γ . Their polarization
8 fractions are also interesting since the polarization puzzle of the B → φK ∗ decay. We study these

8 decays in the perturbative QCD approach based on kT factorization. After calculating of the
0 non-factorizable and annihilation type contributions, in addition to the conventional factorizable
5 contributions, we find that the contributions from the annihilation diagrams are crucial. They
0 give dominant contribution to the strong phases and suppress the longitudinal polarizations. Our

h results agree with the current existing data. We also predict a sizable direct CP asymmetries in
p B+ → K ∗+ρ0 , B0 → K ∗+ρ− , and B+ → K ∗+ω decays, which can be tested by the onc
