Resolution to the B→ϕK∗ polarization puzzle

We resolve the B→ϕK∗ polarization puzzle by postulating a smaller B→K∗ form factor A0≈0.3 and by adding penguin annihilation and nonfactorizable contributions from the perturbative QCD approach. If this explanation is valid, the penguin-dominated modes governed by the B→K∗ form factors, such as B+→K∗+K∗0 and B0→K∗0K¯∗0, should exhibit similar polarization fractions. Our resolution is compared with others in the literature, and experimental discrimination is proposed.
