Abstract：
Based on a data sample of 384 million BB pairs collected with the BABAR detector at the PEP-Ⅱ asymmetric e⁺e^－ storage ring, we measure branching fractions, direct CP, isospin and lepton-flavor asymmetries for the rare decays B→K^(*)l⁺l^－ in two di-lepton mass bins above and below the J/ψ resonance. For the B→K^*l⁺l^－ decay, we also measure the K^* longitudinal polarization fraction and the di-lepton forward-backward asymmetry.
