Hadronic cross section of $e^{+}{e}^{-}$ annihilation at bottomonium energy region

Abstract

The Born cross section and dressed cross section of $e^{+}{e}^{-}$ to $b\bar{b}$ and the total hadronic cross section in $e^{+}{e}^{-}$ annihilation in the bottomonium energy region are calculated based on the Rb values measured by the BaBar and Belle experiments. The data are used to calculate the vacuum polarization factors in the bottomonium energy region, and to determine the resonant parameters of the vector bottomonium(-like) states, the Y(10750), Upsilon(5S), and Upsilon(6S).
