General analysis of lepton polarizations in rare B -> K*l(+)l(-) decay beyond the standard model

The general analysis of lepton polarization asymmetries in rare B --> K*l()l(-) decay is investigated. Using the most general, model independent effe ctive Hamiltonian, the general expressions of the longitudinal, normal and transversal polarization asymmetries for l(-) and l(+) and combinations of them are presented. The dependence of lepton polarizations and their combin ations on new Wilson coefficients are studied in detail. Our analysis shows that the lepton polarization asymmetries are very sensitive to the scalar and tensor type interactions, which will be very useful in looking for new physics beyond the standard model.
