论文摘要
$ e^+e^ - $至$ b \ bar {b} $的出生横截面和穿着的横截面和$ e^+e^ - $ e^+e^ - $ e^+E^ - $ e^ - $ nihilation的总强化横截面的$ e^+e^ - $ e^ - $ nihilation $ e^ - $ e^ - 基于巴巴尔和贝尔实验测量的RB值计算。数据用于计算底部能量区域中的真空极化因子，并确定矢量底部（类似）状态的谐振参数，Y（10750），Upsilon（5s）和Upsilon（6s）。
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).
