Dark matter particles may interact with other dark matter particles via a new force mediated by a dark photon, A′, which would be the dark-sector analog to the ordinary photon of electromagnetism. The dark photon can obtain a highly suppressed mixing-induced coupling to the electromagnetic current, providing a portal through which dark photons can interact with ordinary matter. This review focuses on A′ scenarios that are potentially accessible to accelerator-based experiments. We summarize the existing constraints placed by such experiments on dark photons, highlight what could be observed in the near future, and discuss the major experimental challenges that must be overcome to improve sensitivities.

在加速器处搜索暗光子
暗物质粒子可以通过暗光子A '介导的新力与其他暗物质粒子相互作用,暗光子A ' 将是暗区模拟电磁学的普通光子。暗光子可以获得高度抑制的与电磁电流的混合感应耦合,提供了一个入口,暗光子可以通过这个入口与普通物质相互作用。本综述重点关注基于加速器的实验可能访问的A ' 场景。我们总结了此类实验对暗光子的现有限制,强调了在不久的将来可以观察到的情况,并讨论为提高灵敏度必须克服的主要实验挑战。
