Measurement of the e[superscript +]e[superscript -] -->bb̅ Cross Section between [sqrt s]=10.54 and 11.20 GeV
We report e[superscript +]e[superscript -]→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, separate...

description | We report e[superscript +]e[superscript -]→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. |
