Abstract

We use momentum correlations as physical observables in \stackrel\ensuremath→BK^*l⁺l^\ensuremath- 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.
