Description

In a sample of 471 million BB events collected with the BABAR detector at the PEPII e+e- collider we study the rare decays B->K(*)l+l-, where l+l- is either e+e- or mu+mu-. We report results on partial branching fractions and isospin asymmetries in six bins of di-lepton mass squared. We further present CP and lepton-flavor symmetries for di-lepton masses below and above the J/Psi resonance. We find no evidence of CP or lepton-flavor violation. The partial branching fractions and isospin asymmetries are consistent with the Standard Model predictions and results from other experiments.
