解析计算SM中电子混合链图传播下Compton散射微分截面
Accurate calculation of the differential cross section of compton scattering with electron mixed chain propagator in SM
摘要
Abstract
By using the electroweak standard model (SM),we analyzed the framework of electron mixed chain propagator which composed 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 dσSM(chain)/acosθis counted accurately.This result is compared with the lowest order differential cross section dσ(tree)/dcosθ and the electronic chain propagator Compton scattering differential cross section uσQED(chain) /acosθ in quantum electrodynamics (QED).It can be seen that dσSM(chain)/dcosθ can show the radiation correction more subtly than dσQED(chain)/dcosθ.关键词
