Abstract: (APS)

We study the lepton forward-backward asymmetry AFB and the longitudinal K* polarization FL, as well as an observable P2 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.
