暗光子

The Dark Photon

Marco Fabbrichesi, Emidio Gabrielli, Gaia Lanfranchi

摘要:

暗光子是一种新的规范玻色子,它的存在已被证实。它是暗的,因为它来自于一个假想的暗扇区的对称性,该暗扇区包括在标准模型相互作用下完全中性的粒子。尽管这种新的规范玻色子很暗,但由于它与普通可见光子的动力学混合,它可以被探测到。我们从理论和实验的角度来回顾它的物理。我们讨论有质量和无质量情况的区别。我们解释了暗光子如何进入实验室,天体物理学和宇宙学观测以及暗物质物理。我们调查了当前和未来的实验限制的参数的无质量和大质量的暗光子,以及相关的界限毫荷费米子。

英文摘要:

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.
