论文摘要
我们在线性极化探针光子（$ \ \vecγ'$）与线性极化激光束（$ \ vec l $）的相互作用中研究非线性Breit-wheeler工艺$ \vecγ' + \ vec l \ to e^ + + e^ - $。特别是，当初始状态的光子和激光束的极化是相互垂直的或平行的，我们考虑了总横截面和方位角电子的不对称性。考虑到强烈的激光束和强场渐近线，我们基本上探索了多光子动力学。根据初始运动条件，不对称性表现出一些非单调行为。它敏感地取决于激光脉冲持续时间。我们的结果为研究量子电动力学中的非线性多光子效应提供了额外的知识，并可以用于即将到来的激光设施的计划实验。
We study the non-linear Breit-Wheeler process $\vec γ' + \vec L \to e^+ + e^-$ in the interaction of linearly polarized probe photons ($\vec γ'$) with a linearly polarized laser beam ($\vec L$). In particular, we consider the asymmetry of the total cross section and the azimuthal electron distributions when the polarizations of the photon and laser beams in the initial state are mutually perpendicular or parallel. Considering intense laser beams and the strong field asymptotic we explore essentially the multi-photon dynamics. The asymmetry exhibits some non-monotonic behavior depending on initial kinematic conditions; it depends sensitively on the laser pulse duration. Our results provide additional knowledge for studying non-linear multi-photon effects in quantum electrodynamics and may be used in planning experiments in upcoming laser facilities.
