We present a measurement of the parameters of the Upsilon(10580) resonance based on a dataset collected with the BABAR detector at the SLAC PEP-II asymmetric B factory. We measure the total width Gamma(tot)=(20.7 +/- 1.6 +/- 2.5) MeV, the electronic partial width Gamma(ee)=(0.321 +/- 0.017 +/- 0.029) keV and the mass M=(10579.3 +/- 0.4 +/- 1.2) MeV/c(2).

Abstract
We present a measurement of the parameters of the Upsilon(10580) resonance based on a dataset collected with the BABAR detector at the SLAC PEP-II asymmetric B factory. We measure the total width Gamma(tot)=(20.7 +/- 1.6 +/- 2.5) MeV, the electronic partial width Gamma(ee)=(0.321 +/- 0.017 +/- 0.029) keV and the mass M=(10579.3 +/- 0.4 +/- 1.2) MeV/c(2).File in questo prodotto:
