BABAR Measurements on B->K(*)l+l- Rates and Rate Asymmetries

Abstract

Based on 471 million BB pairs collected with the BABAR detector at the PEP-II e+e- collider, we perform a series of measurements on rare decays B->K(*)l+l-, where l+l- is either e+e- or mu+mu-. The measurements include total branching fractions, and partial branching fractions in six bins of di-lepton mass-squared. We also measure isospin asymmetries in the same six bins. Furthermore, we measure direct CP and lepton flavor asymmetries for di-lepton mass below and above the J/Psi resonance. Our measurements show good agreement with both Standard Model predictions and measurements from other experiments.
