【摘要】 采用电弱统一标准模型（SM）,分析了由参与电弱相互作用的各种混合圈构成的光子γ,中间玻色子Zo重整化链图传播子的构架方式,并完成了相关解析计算,进而获得了γ,Z₀重整化混合圈链图传播子的解析计算结果.作者又将γ,Z₀混合圈链图传播子D_γ^{（m-chain）}（s）,D_Z^{（m-chain）}（s）和D_γZ^{（m-chain）}（s）应用到粒子反应e■→f■中,精确计算了e■→f■反应总截面σ_SM^（chain）.通过与LEP实验组的实验观测值的比较,发现本文理论计算结果比最低（树图）阶的结果与实验吻合更好.更多还原

【Abstract】 Based on the electroweak standard model（SM）,we systematically investigated the framework ofγ,Z₀mixed chain propagators,which composed of series of different physical loops in electroweak interaction, and achieved the relevant analytical calculation.By applying they,Z₀mixed chain propagators D_γ^m·chain（s）,D_Z^m·chain（s）and D_γZ^m·chain（s） to e■→f ■,the total cross sectionsσ_SM^chain were calculated accurately. Compared with the experimental data of LEP,the numerical results indicated that our results are in better agreement with the experiment data than Born tree level predictions.更多还原
