A precision measurement of the Υ{hooked}′ meson mass

Physics Letters B, Volume 135, No. 5-6, Year 1984

The e+e--storage ring DORIS II provides polarized beams with polarizations up to 80% in the energy range of the Υ{hooked}′ meson. The method of resonance depolarization allows the average beam energy to be determined to a precision of ±0.1 MeV. An energy scan of the hadronic cross section over the resonance range with the detectors ARGUS and Crystal Ball determines the Υ{hooked}′ mass to be (10023.1 ± 0.4) MeV. © 1984.
