The refined similarity hypotheses (RSH) and their extension to passive scalar (RSH-P) are tested experimentally using simultaneous velocity and scalar data in a turbulent jet. Different from the single-point hot-wire probe in a previous experimental test, a combined particle image velocimetry and planar laser induced fluorescence technique enable us to obtain the test data without applying Tayl...

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), ...

A proposal is presented for detecting new physics at a B factory running at the Υ(3S) resonance by testing lepton universality to the few percent level in the leptonic decays of the Υ(1S) and Υ(2S) resonances tagged by the dipion in the chain decay: Υ(3S) → π + π

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...

We analyze the ππ production amplitudes in the excited Υ decay processes, Υ (2S) → Υ (1S)ππ, Υ (3S) → Υ (1S)ππ and Υ (3S) → Υ (2S)ππ, and the ππ and KK̄ production amplitudes in the charmonium decay processes, ψ(2S) → J/ψππ and J/ψ → φππ, φKK. The amplitudes are parametrized by the sum of Breit-Wigner amplitudes for the σ and the other relevant particles and of the direct 2π-production amplitude...

The question of whether mesospheric OH(υ) rotational population distributions are in equilibrium with the local kinetic temperature has been debated over several decades. Despite several indications for the existence of non-equilibrium effects, the general consensus has been that emissions originating from low rotational levels are thermalized. Sky spectra simultaneously observing several vibra...
