چکیده

We search for single-photon decays of the Υ(1S) resonance, Υ → γ + invisible, where the invisible state is either a particle of definite mass, such as a light Higgs boson A⁰, or a pair of dark matter particles, χχ. Both A⁰ and χ are assumed to have zero spin. We tag Υ(1S) decays with a dipion transition Υ(2S) → π⁺π⁻Υ(1S) and look for events with a single energetic photon and significant missing energy. We find no evidence for such processes in the mass range m(A⁰) ≤ 9.2 GeV and m(χ) ≤ 4.5 GeV in the sample of 98 × 10⁶ Υ(2S) decays collected with the BABAR detector and set stringent limits on new physics models that contain light dark matter states.

Production of the Η B (ns) States

The rates for magnetic dipole (M1) transitions Υ(nS) → ηb(n S) + γ, n ≤ n, are compared. The photon energies for allowed (n = n) M1 transitions are very small, so hindered (n < n) transitions could be more favorable for discovering the ηb(1S, 2S). The question then arises whether Υ(2S) or Υ(3S) is a better source of ηb(1S). Whereas one nonrelativistic model favors ηb(1S) production from Υ(2S), ...

CLEO Results on Upsilons a

I present highlights of recent CLEO studies on the Υ(1S), Υ(2S), and Υ(3S). The preliminary results presented here include the first observation of a hadronic cascade in the Υ system not involving pions, Υ(3S) → γχ b1,2 (2P) followed by χ b1,2 (2P) → ωΥ(1S). I also present preliminary results on a search for inclusive ψ production in Υ(1S) decays. I end with a search for nine different two body...
