Abstract: | We report e + e − → b ¯ b 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. |
