By colliding highly intense optical laser pulses with ultra relativistic electrons, obtainable from laser-plasma accelerators, the critical field of quantum electrodynamics (QED) becomes accessible with contemporary technology. Moreover, strong-field QED effects like quantum radiation reaction, prolific electron-positron pair production, and QED cascades will influence laser-matter and laser-plasma experiments at upcoming facilities like the Extreme Light Infrastructure (ELI). Laser-based strong-field experiments will therefore test the standard model of particle physics at the ``intensity frontier'', which is complementary to searches for new particles at the ``energy frontier'' with conventional particle collider experiments. In the regime where on the one hand collective plasma effects and the depletion of the laser field become important and on the other classical electrodynamics and also the perturbative treatment of QED break down, the QED particle-in-cell (PIC) approach is used for numerical calculations. Here, we suggest to investigate the validity of state-of-the-art QED-PIC calculations, to consider new phenomena not hitherto taken into account, and to analyze novel types of experiments which could probe the interplay between plasma physics and highly nonlinear QED processes.

通过将高强度的激光脉冲与可从激光等离子体加速器获得的超相对论电子碰撞，量子电动力学（QED）的临界领域变得可用当代技术实现。此外，量子辐射反应、大量电子-正电子对产生和QED级联等强场QED效应将影响极光基础设施（ELI）等即将建成的设施的激光物质和激光等离子体实验。因此，基于激光的强场实验将在"强度前沿“测试粒子物理学的标准模型，这是对利用传统粒子对撞机实验在”能量前沿“寻找新粒子的补充。在该制度中，一方面集体等离子体效应和激光场的耗尽变得重要，另一方面经典电动力学和微扰处理的QED打破，QED粒子在细胞（PIC）的方法被用于数值计算。在这里，我们建议调查国家的最先进的QED-PIC计算的有效性，考虑到迄今尚未考虑到的新现象，并分析新类型的实验，可以探测等离子体物理和高度非线性QED过程之间的相互作用。
