论文摘要
最近显示，电磁环境的明确描述需要电磁电位。仅电场和磁场的知识不足，并且可能导致错误。该演示的后果在这里应用于传播场，例如激光场。量规不变性被对称保存所取代。这种改变使您可以了解量子电动力学（QED）中扰动扩张的已知失败是从QED不完整的事实中得出的。它不包含其强场限制。该演示中固有的是强场耦合常数和带电粒子的质量壳的强场变化。随之而来的是各种重要的物理后果，包括Feynman图的指导丧失。质疑QED精度的测试的含义，因为此类评估仅适用于扰动QED，但不适用于完整QED所需的扩展。
It was shown recently that unambiguous description of electromagnetic environments requires electromagnetic potentials; knowledge only of electric and magnetic fields is insufficient and can lead to error. Consequences of that demonstration are here applied to propagating fields, such as laser fields. Gauge invariance is replaced by symmetry preservation. This alteration makes it possible to understand how the known failure of the convergence of perturbation expansions in quantum electrodynamics (QED) follows from the fact that QED is incomplete; it does not contain its strong-field limit. Inherent in that demonstration are the strong-field coupling constant and the strong-field alteration of the mass shell of a charged particle. A variety of physically important consequences ensue, including the loss of guidance from Feynman diagrams. The meaning of tests for the precision of QED is questioned since such evaluations apply only to perturbative QED, but not to extensions required for complete QED.
