Polarized lepton pair forward–backward asymmetries in B → K∗l+l− decay beyond the standard model

We study the polarized lepton pair forward–backward asymmetries inB → K∗l+l− decay using the most general, model independent form of the effective Hamiltonian. We present the general expression for nine double–polarization forward–backward asymmetries. It is shown that, the study of the forward–backward asymmetries of the doubly–polarized lepton pair is a very useful tool for establishing new physics beyond the standard model.
