Abstract

Results are presented on χ_b1,₂(2P) → χΥ(1S) transitions from e⁺e^- → Υ(3S) → γχ_b1,₂(2P) decays. The data were collected with the BABAR detector at the PEP-II asymmetric-energy e⁺e^- collider at SLAC. The integrated luminosity of the data sample is 28.0 fb^-1, corresponding to 121.3 × 10⁶ Υ(3S) decays. Signals of χ_b1,₂(2P) are observed over a negligible background. Improved precision measurements of branching fractions are obtained. First measurements of the χ_b1,2(2P) angular distributions are performed. No evidence is found for the presence of χ_b0(2P) → ωΥ(1S) decay mode.
