] | Inspired by the small longitudinal polarizations (LPs) of $B\to K^* \phi$ decays observed by BELLE and BABAR, we revise the theoretical uncertainties of perturbative QCD approach for determining hard scales of B decays, we find that the LPs of $B\to K^* \phi$ could approach to 60% while the branching ratios (BRs) could... |
