Abstract

Using a 4.19 fb^-1 data sample collected with the CLEO II detector at the Cornell Electron Storage Ring, we have searched for dipion transitions between pairs of Y resonances at center of mass energies E_c.m. = 10.58 GeV and E_c.m. = 10.52GeV. We obtain the 90% confidence level upper limits B(Y(4S) →Y(2S)π⁺π^-)<3.9×10^-4 and B(Y(4S)→Y(1S)π⁺π^-)<1.2×10 ^-4. We also observe the transitions Y(3S)→Y(1S)π⁺π^-, Y(3S)→Y(2S)π⁺π^-, and Y(2S)→Y(1S)π⁺π^-, from which we measure the cross sections for the radiative processes e⁺e^-→Y(3S)γ and e⁺e^-→Y(2S)γ. We obtain σ_ee→Y(3S)γ = (17.8±3.0±1.7) pb and σ_ee→Y(2S)γ=(15.5±1.3±1.4) pb at E_c.m. = 10.58 GeV, and σ_ee→Y(3S)γ=(27.3±5.0±2.6) pb and σ_ee→Y(2S)γ=(16.3±1.8±1.5) pb at E_c.m. = 10.52 GeV, which we compare with theoretical predictions.
