论文摘要
深色光子是一种新的仪表，其存在已被猜测。它是黑暗的，因为它源于在标准模型相互作用下完全中立的假设黑暗扇区的对称性。虽然是黑暗的，但由于其动力学混合与普通的，可见的光子的混合，因此可以检测到这种新的仪表。我们从理论和实验的角度回顾了它的物理学。我们讨论大规模和无质量案例之间的区别。我们解释了深色光子如何进入实验室，天体物理和宇宙学观察以及暗物质物理学。我们对无质量和巨大的深色光子参数的当前和未来实验限制以及毫米充电费米子的相关边界。
The dark photon is a new gauge boson whose existence has been conjectured. It is dark because it arises from a symmetry of a hypothetical dark sector comprising particles completely neutral under the Standard Model interactions. Dark though it is, this new gauge boson can be detected because of its kinetic mixing with the ordinary, visible photon. We review its physics from the theoretical and the experimental point of view. We discuss the difference between the massive and the massless case. We explain how the dark photon enters laboratory, astrophysical and cosmological observations as well as dark matter physics. We survey the current and future experimental limits on the parameters of the massless and massive dark photons together with the related bounds on milli-charged fermions.
