论文摘要
背景字段中的QED扰动理论已被猜想，以分解足够高的场强度。然而，野外理论的高强度行为与其高能量（UV）行为交织在一起。在这里，我们表明QED的紫外线修饰改变了可观察到的高强度行为。具体而言，我们在QED中使用额外的Pauli项研究了在QED恒定的跨场中的非线性康普顿散射。在紫外线修改理论中，横截面表现出比普通QED的强度更快的幂律缩放。
QED perturbation theory in a background field has been conjectured to break down for sufficiently high field intensity. The high-intensity behavior of a field theory is however intertwined with its high-energy (UV) behavior. Here we show that a UV modification of QED changes the high-intensity behaviour of observables. Specifically we study non-linear Compton scattering in a constant crossed field in QED with an additional Pauli term. In the UV modified theory the cross section exhibits a faster power-law scaling with intensity than in ordinary QED.
