Measurement of the total width, the electronic width, and the mass of the Υ(10580) resonance


We present a measurement of the parameters of the Υ(10580) resonance based on a dataset collected with the BABAR detector at the SLAC PEP-II asymmetric B factory. We measure the total width Γtot=(20.7±1. 6±2.5)MeV, the electronic partial width Γee=(0.321±0. 017±0.029)keV and the mass M=(10579.3±0.4±1.2)MeV/c2. © 2005 The American Physical Society.
