Abstract

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. Expected final online publication date for the Annual Review of Nuclear and Particle Science, Volume 71 is September 2021.

在加速器上搜索暗光子

暗物质粒子可能通过暗光子a′介导的新力与其他暗物质粒子相互作用，a′将是类似于普通电磁光子的暗扇区。暗光子可以获得与电磁电流的高度抑制的混合诱导耦合，提供一个暗光子可以与普通物质相互作用的入口。这篇综述的重点是基于加速器的实验可能获得的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，并讨论了必须克服的主要实验挑战，以提高灵敏度。《核与粒子科学年度评论》第71卷预计最终在线出版日期为2021年9月。请参阅http://www.annualreviews.org/page/journal/pubdates用于修订估算。

期刊介绍： The Annual Review of Nuclear and Particle Science is a publication that has been available since 1952. It focuses on various aspects of nuclear and particle science, including both theoretical and experimental developments. The journal covers topics such as nuclear structure, heavy ion interactions, oscillations observed in solar and atmospheric neutrinos, the physics of heavy quarks, the impact of particle and nuclear physics on astroparticle physics, and recent advancements in accelerator design and instrumentation. One significant recent change in the journal is the conversion of its current volume from gated to open access. This conversion was made possible through Annual Reviews' Subscribe to Open program. As a result, all articles published in the current volume are now freely available to the public under a CC BY license. This change allows for greater accessibility and dissemination of research in the field of nuclear and particle science.
