Direct CP, Lepton Flavor, and Isospin Asymmetries in the Decays B -> K((*))l(+)l(-)

We measure branching fractions and integrated rate asymmetries for the rare decays B→K(*)l+l-, where l+l- is either e+e- or μ+μ-, using a sample of 384×106 BB̄ events collected with the BABAR detector at the PEP-II e+e- collider. We find no evidence for direct CP or lepton-flavor asymmetries. Howeve...
