论文摘要
本报告回顾了几十年来观察线性Breit-theeler工艺（$γγ\ Rightarrow E^+E^ - $）和真空双偏双发性在高能粒子和重离子碰撞器实验中的努力。这份报告是由Star最近的观察结果激励的，试图总结与高能实验中的极化$γγ\ rightarrow l^+l^ - $测量相关的关键问题。为此，我们首先要回顾历史背景和基本理论发展，然后重点介绍数十年来高能撞机实验的进步。特别关注实验方法的演变，以应对各种挑战以及明确识别线性BREIT轮毂过程所需的苛刻检测器能力并检测真空双折射的特征。我们通过讨论结束了报告，然后查看利用这些发现并在以前未开发的制度中测试QED的近乎想象的机会。
This Report reviews the effort over several decades to observe the linear Breit-Wheeler process ($γγ\rightarrow e^+e^-$) and vacuum birefringence in high-energy particle and heavy-ion collider experiment. This Report, motivated by STAR's recent observations, attempts to summarize the key issues related to the interpretation of polarized $γγ\rightarrow l^+l^-$ measurements in high-energy experiments. To that end, we start by reviewing the historical context and essential theoretical developments, before focusing on the decades of progress made in high-energy collider experiments. Special attention is given to the evolution in experimental approaches in response to various challenges and the demanding detector capabilities required to unambiguously identify the linear Breit-Wheeler process and to detect the signatures of vacuum birefringence. We close the report with a discussion, followed by a look at near-future opportunities for utilizing these discoveries and for testing QED in previously unexplored regimes.
