摘要:

我们提出了一个全面的审查千电子伏规模的无菌中微子暗物质,收集意见和见解,从所有涉及的学科-宇宙学,天体物理学,核,粒子物理学-在每种情况下,从理论和实验/观测的角度来看。在回顾了活跃中微子在粒子物理学、天体物理学和宇宙学中的作用之后,我们将重点放在暗物质之谜中的惰性中微子上。在这里,我们首先回顾了无菌中微子暗物质的物理动机,基于纯粹的冷暗物质场景中的挑战和紧张局势。然后,我们全面的讨论,严格总结所有已知的约束产生的天体物理观测,实验室实验和理论的考虑,无菌中微子暗物质。在这种情况下,我们提供了一个平衡的话语可能是积极的信号,从X射线观测。本文的另一个重点是粒子物理模型的构建,旨在解释如何在基本粒子物理学标准模型之外的具体环境中产生千电子伏级质量的无菌中微子。本文最后对当前和未来的天体物理学和实验室研究进行了广泛的回顾,突出了新的想法及其实验挑战,以及发现无菌中微子的未来前景。

英文摘要:

We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and particle physics - in each case viewed from both theoretical and experimental/observational perspectives. After reviewing the role of active neutrinos in particle physics, astrophysics, and cosmology, we focus on sterile neutrinos in the context of the Dark Matter puzzle. Here, we first review the physics motivation for sterile neutrino Dark Matter, based on challenges and tensions in purely cold Dark Matter scenarios. We then round out the discussion by critically summarizing all known constraints on sterile neutrino Dark Matter arising from astrophysical observations, laboratory experiments, and theoretical considerations. In this context, we provide a balanced discourse on the possibly positive signal from X-ray observations. Another focus of the paper concerns the construction of particle physics models, aiming to explain how sterile neutrinos of keV-scale masses could arise in concrete settings beyond the Standard Model of elementary particle physics. The paper ends with an extensive review of current and future astrophysical and laboratory searches, highlighting new ideas and their experimental challenges, as well as future perspectives for the discovery of sterile neutrinos.
