论文摘要
激光背景中的散射过程退化为与激光的不可观察的光子共线发射。我们确定了这种退化性分量和指定的过程和可观察物，从而在高激光强度下获得了这些包容性可观察物的领先强度依赖性，并且可以正确地对细胞结构常数（所有回路，所有发射）正确地纠正。结果表明，指数强度的依赖性不同于Narozhny-Ritus猜想对强场中量子电动力学的高强度行为所预测的。
Scattering processes in laser backgrounds are degenerate to the emission of unobservable photons collinear with the laser. We identify processes and observables for which such degeneracies factorise and exponentiate, obtaining the leading-order intensity dependence of these inclusive observables at high laser intensity, correct to all orders in the fine-structure constant (all loops, all emissions). The results show an exponential intensity dependence distinct from that predicted by the Narozhny-Ritus conjecture on the high-intensity behaviour of quantum electrodynamics in strong fields.
