Measurement of angular asymmetries in the decays B → K*ℓ^+ℓ^−

We study the lepton forward-backward asymmetry A_(FB) and the longitudinal K* polarization F_L, as well as an observable P_2 derived from them, in the rare decays B→K*ℓ^+ ℓ^−, where ℓ^+ ℓ^− is either e^+e^− or μ^+μ^−, using the full sample of 471 million BB events collected at the Υ(4S) resonance with the BABAR, detector at the PEP-II e^+e^− collider. We separately fit and report results for the K*0(892)ℓ^+ℓ^− and K*^+(892)ℓ^+ℓ^− final states, as well as their combination K*ℓ^+ℓ^−, in five disjoint dilepton mass-squared bins. An angular analysis of B^+ →K*+ℓ^+ ℓ^− decays is presented here for the first time
