AI总结：
本研究对比WarpX与GUINEA-PIG在电子正电子对撞中的表现，WarpX能自洽处理QED效应产生的对，且在ILC和超紧碰撞场景下具有显著加速优势，为多TeV对撞机提供更高效建模。
摘要：
作为Snowmass'21规划演习的一部分，先进加速器概念社区提议开发多TeV线性对撞机，并考虑了这些机器的束-束效应。此类对撞机在高破坏性状态下运行，从QED效应产生大量电子-正电子对。因此，需要对由这些对产生的场进行自洽处理，这在诸如GUINEA-PIG等最先进的束-束代码中尚未实现。WarpX是一个并行、开源、可移植的粒子胞内代码，拥有活跃的开发者社区，在相对论激光-束相互作用中模拟QED过程，包括光子和对的产生。然而，其应用于束-束碰撞尚未得到充分探索。在本工作中，我们在ILC和超紧碰撞场景下，将WarpX的光度谱、光子谱和相干产生过程与GUINEA-PIG进行基准测试。我们的性能比较展示了WarpX显著的加速优势，确保在多TeV能量下对电子-正电子碰撞进行更稳健和高效的建模。
英文摘要：
As part of the Snowmass'21 planning exercise, the Advanced Accelerator Concepts community proposed developing multi-TeV linear colliders and considered beam-beam effects for these machines. Such colliders operate under a high disruption regime with an enormous number of electron-positron pairs produced from QED effects. Thus, it requires a self-consistent treatment of the fields produced by the pairs, which is not implemented in state-of-the-art beam-beam codes such as GUINEA-PIG. WarpX is a parallel, open-source, and portable particle-in-cell code with an active developer community that models QED processes with photon and pair generation in relativistic laser-beam interactions. However, its application to beam-beam collisions has yet to be fully explored. In this work, we benchmark the luminosity spectra, photon spectra, and coherent production process from WarpX against GUINEA-PIG in the ILC and ultra-tight collision scenarios. Our performance comparison demonstrates a significant speed-up advantage of WarpX, ensuring a more robust and efficient modeling of electron-positron collisions at multi-TeV energies.
