摘要 采用光子与电子(正电子)的最小电磁耦合模型,获得了光子链图传播子重整化的有限量。对其辐射修正作了相关的计算和讨论,从而得到了电子-正电子碰撞在链近似下的散射截面,并与最低阶的散射截面作了比较. In the minimum electromagnetism coupling model of interaction between photon and electron (antielectron), we obtain the renormalization finite quantity of photon chain propagator. We calculate its radialization correction and make the correlative discussion, obtain the cross section of electron-antielectron collision under chain approximation, and compare the tree-level cross section with the cross section under chain approximation.
