暗(或隐藏的)光子是一个大质量的U(1)规范玻色子，理论上认为它是暗力的媒介，也是暗物质的候选者。通过探测暗光子与标准模型光子的动力学混合所产生的能量过剩，可以用轴子腔示光镜探测暗光子。因此，通过计算对应的暗光子到光子的耦合因子，可以将光晕轴子排除极限转换为竞争暗光子参数极限。与其他暗光子排除相比，这一计算允许灵敏度提高约四个数量级，并且可以使用现有数据来实现。我们介绍了如何转换日光轴子搜索极限，并从已发表的搜索中总结了相关的实验参数。此外，我们还包含了可用于生成本文所述情况下的暗光子排除极限的代码。最后，基于已有的日光轴子搜索，我们给出了暗光子和标准模型光子之间的动力学混合系数的极限。
The dark (or hidden) photon is a massive U(1) gauge boson theorized as a dark force mediator and as a dark matter candidate. Dark photons can be detected with axion cavity haloscopes by probing for a power excess caused by the dark photon's kinetic mixing with Standard Model photons. Haloscope axion exclusion limits may therefore be converted into competitive dark photon parameter limits via the calculation of a corresponding dark photon to photon coupling factor. This calculation allows for an improvement in sensitivity of around four orders of magnitude relative to other dark photon exclusions and may be attained using existing data. We present how one converts haloscope axion search limits and a summary of relevant experimental parameters from published searches. In addition, we have included the code that can be used to generate our dark photon exclusion limits for the cases described in this paper. Finally, we present limits on the kinetic mixing coefficient between dark photons and the Standard Model photons based on existing haloscope axion searches.
