协变量子电动力学的友永，施温格和费曼是用来作为基础的散射问题，涉及电子，正电子和光子的一般治疗。散射过程，包括粒子的产生和湮灭，完全由海森堡的S矩阵描述。它示出，该矩阵的元素可以计算，通过一致使用微扰理论，在精细结构常数的任何所需的顺序。详细的规则进行这样的计算，它表明，从高阶辐射校正所产生的发散可以从S矩阵中删除的质量和电荷重整化的想法一致使用。
The covariant quantum electrodynamics of Tomonaga, Schwinger, and Feynman is used as the basis for a general treatment of scattering problems involving electrons, positrons, and photons. Scattering processes, including the creation and annihilation of particles, are completely described by the S matrix of Heisenberg. It is shown that the elements of this matrix can be calculated, by a consistent use of perturbation theory, to any desired order in the fine-structure constant. Detailed rules are given for carrying out such calculations, and it is shown that divergences arising from higher order radiative corrections can be removed from the S matrix by a consistent use of the ideas of mass and charge renormalization.
