Long distance contributions in B→K*l⁺l^- decays with polarized K*

We use momentum correlations as physical observables in B→K*l⁺l^-decays with K* polarized to study the long distance contributions. We show that these observables are sensitive to the scenarios of the long distance parametrizations. We find that the T-odd observable is directly related to the nonfactorizable effect in the standard model.
