We report results on partial branching fractions and isospin asymmetries in seven bins of dilepton mass-squared. We further present CP and lepton-flavor asymmetries for dilepton masses below and above the J/ψ resonance. We find no evidence for CP or lepton-flavor violation. The partial branching fractions and isospin asymmetries are consistent with the Standard Model predictions and with results from other experiments.en-US©2012 American Physical SocietyBranching fractions (Nuclear physics)CP violation (Nuclear physics)Leptons (Nuclear physics)TextLees, J.
