解析计算SM中电子混合链图传播下Compton散射微分截面(英文)

采用电弱统一标准模型（SM）,对由参与电弱相互作用的各种混合圈构成的电子重整化链图传播子的构架方式作了详细分析,并完成了有关解析计算,进而获得了电子重整化链图传播子的解析计算结果.作者又将此结果应用到Compton散射,精确计算了电子混合链图传播下Compton散射微分截面的解析结果dσ_SM^chain/dcosθ.此外,作者还将计算结果与最低阶微分截面dσ^trcc/dcosθ口和量子电动力学（QED）中电子链图传播下的Compton散射微分截面dσ_QED^chain/dcosθ做了具体的数值计算与对比分析,发现dσ_SM^chain/dcosθ比dσ_QED^chain/dcosθ能更加精细的反应辐射修正效应.

Accurate Calculation of the Differential Cross Section of Compton Scattering with Electron Mixed Chain Propagator in SM

By using the electroweak standard model (SM), we analyzed the framework of electron mixed chain propagator which composes of serious of different physical loops participating in electroweak interaction and completed the relevant analytical calculation. Then, we obtained the analytical result of electron mixed chain propagator. By applying our result to Compton scattering, the differential cross section of Compton scattering is counted accurately. This result is compared with the lowest order differential cross section and the electronic chain propagator Compton scattering differential cross section in quantum electrodynamics (QED). It can be seen that can show the radiation correction more subtly than .quantum electrodynamics (QED), the results indicated that can show the radiation correction more subtly than .
