论文摘要
利用与沃尔科夫（Volkov）在平面波背景中传播的电荷描述相关的量规自由，我们确定了一种新型的量规选择，从而大大简化了理论。这使我们能够在循环极化背景下对标量和费米子物质的传播器进行紧凑的描述。结果表明，许多通常观察到的结构是量规伪像。然后，我们分析了此类费用的一环校正的完整紫外线行为。这使我们能够识别和对比两种物质所需的不同的重量化处方。
Exploiting the gauge freedom associated with the Volkov description of a charge propagating in a plane wave background, we identify a new type of gauge choice which significantly simplifies the theory. This allows us to develop a compact description of the propagator for both scalar and fermionic matter, in a circularly polarised background. It is shown that many of the usually observed structures are gauge artefacts. We then analyse the full ultraviolet behaviour of the one-loop corrections for such charges. This enables us to identify and contrast the different renormalisation prescriptions needed for both types of matter.
