The introduction of a hidden sector of particles and a new very weak interaction with the fundamental Standard Model fermions could explain the anomalies in the muon magnetic moment, the results from scattering experiments searching for Dark Matter and also the antimatter excess in the cosmic rays. The simplest interaction scenario is an additional U(1) gauge symmetry resembling the electromagnetism but with a massive interaction carrier —the dark photon A′. Such a model has a high predictive power and is being extensively tested by past and present experiments. Present status of the dark photon searches is discussed as well as the possible improvements in the near future.

暗光子物理学的结果和观点

引入隐藏的粒子扇区以及与基本标准模型费米子的新的非常弱的相互作用可以解释介子磁矩的异常，散射实验寻找暗物质的结果以及宇宙射线中反物质过量的原因。最简单的交互场景是类似于电磁的U（1）轨距对称性，但具有大量的交互载体-暗光子A '。这种模型具有较高的预测能力，并且正在通过过去和现在的实验进行广泛测试。讨论了暗光子搜索的现状以及在不久的将来可能的改进。
