论文摘要
重型离子碰撞中产生的极大的电磁场提供了对新型可观察物的访问，这些新可观察物有望限制夸克 - 胶状等离子体的各种关键运输特性，并可以帮助解决QCD中的一个出色的难题：强大的CP问题。在这篇综述中，我们简要概述了这些电磁场的理论和实验表征。在审查了当前状态后，强调了一种可观察到的物体 - 依赖电荷的流程 - 我们讨论了测量和理论预测之间的各种差异。最后，为了帮助解决差异，我们建议新的测量和理论思想。
The extremely large electromagnetic fields generated in heavy-ion collisions provide access to novel observables that are expected to constrain various key transport properties of the quark-gluon plasma and could help solve one of the outstanding puzzles in QCD: the strong CP problem. In this review we present a brief overview of the theoretical and experimental characterization of these electromagnetic fields. After reviewing the current state, emphasising one of the observables -- the charge-dependent flow -- we discuss the various discrepancies between the measurements and theoretical predictions. Finally, to help resolve the discrepancies, we suggest new measurements and theoretical ideas.
