Description
We report measurements made with the CLEO detector at the Cornell Electron Storage Ring (CESR) of the total cross section for e+e-→hadrons at the UPSILON(1S), UPSILON(2S), and UPSILON(3S), and in the nearby nonresonant continuum. We find R = 3.77 +- 0.06 (statistical) +- 0.24 (systematic) for the ratio of the nonresonant hadronic cross section to the cross section for muon-pair production at a center-of-mass total energy W = 10.4 GeV. For the leptonic decay widths GAMMA/sub e/e of the UPSILON(1S), UPSILON(2S), and UPSILON(3S) we obtain 1.30 +- 0.05 +- 0.08, 0.52 +- 0.03 +- 0.04 , and 0.42 +- 0.04 +- 0.03 keV, respectively
