Search for new physics in the B→K(*)l+l decays at BABAR

  • 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.

Search for new physics in the B→K(*)l+l decays at BABAR

  • Institut de Physique Nucleaire de Lyon, Villeurbanne 69622, France

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.
