Search for a Light Higgs Boson Decaying to Two Gluons or ss̅ in the Radiative Decays of ϒ(1s)
(American Physical Society, 2013-08-06)
We search for the decay ϒ(1s) → γA⁰, A⁰ → gg or ss̅, where A⁰ is the pseudoscalar light Higgs boson predicted by the next-to-minimal supersymmetric Standard Model. We use a sample of (17.6 ± 0.3) x10⁶ ϒ(1s) mesons produced ...
Search for a Low-Mass Scalar Higgs Boson Decaying to a Tau Pair in Single-Photon Decays of ϒ(1s)
(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) ...
