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