    • Search for a Low-Mass Scalar Higgs Boson Decaying to a Tau Pair in Single-Photon Decays of ϒ(1s) 

      Lees, J. P.; Poireau, V.; Tisserand, V.; Garra Tico, J.; Grauges, E.; Palano, A.; Eigen, G.; Izen, Joseph M.; Lou, Xinchou; BaBar Collaboration (American Physical Society, 2013-10-10)
      We search for a low-mass scalar CP-odd Higgs boson, A⁰, produced in the radiative decay of the upsilon resonance and decaying into a τ⁺τ⁻ pair: ϒ(1S)→γA⁰. The production of ϒ(1S) mesons is tagged by ϒ(2S) π⁺π⁻ ϒ(1S) ...
