Aubert, B. et al. (2009) Measurement of the e+e-→bb¯ Cross Section between s=10.54 and 11.20 GeV. Physical Review Letters, 102 (1). 012001. ISSN 0031-9007Metadata only available from this repository.
We report e+e-→bb̅ cross section measurements by the BABAR experiment performed during an energy scan in the range of 10.54 to 11.20 GeV at the SLAC PEP-II e+e- collider. A total relative error of about 5% is reached in more than 300 center-of-mass energy steps, separated by about 5 MeV. These measurements can be used to derive precise information on the parameters of the Υ(10860) and Υ(11020) resonances. In particular we show that their widths may be smaller than previously measured.
