Abstract

We determine the di-electron widths of the Υ(1S), Υ(2S), and Υ(3S) resonances with better than 2% precision by integrating the cross-section of e⁺e^- → Υ over the e ⁺e^- center-of-mass energy. Using e⁺e ^- energy scans of the Υ resonances at the Cornell Electron Storage Ring and measuring Υ production with the CLEO detector, we find di-electron widths of 1.252 ± 0.004 (σ_stat) ± 0.019 (σ_syst) keV, 0.581 ± 0.004 ± 0.009 keV, and 0.413 ± 0.004 ± 0.006 keV for the Υ(1S), Υ(2S), and Υ(3S), respectively.
