利用condensed matter系统研究轻暗物质

Searches for light dark matter using condensed matter systems

Yonatan Kahn, Tongyan Lin

摘要:

确定暗物质(DM)的性质一直是粒子物理学的一个紧迫问题。在面对越来越强大的排除和零的结果,从大曝光搜索TeV规模DM与核相互作用,大量的注意力已经转移到更轻的(亚GeV)DM候选人。通过观察DM散射离开目标系统来直接探测银河系中的光暗物质,与以前的搜索相比,需要新的方法。较轻的DM粒子具有较少的可用动能,并且实现DM和目标之间的运动学匹配要求正确处理凝聚态系统中的集体激发,例如带电准粒子或声子。在这种情况下,靶材料的凝聚态物理是至关重要的,需要跨学科的方法。在这篇综述中,我们提供了一个独立的介绍直接检测keV-GeV DM与凝聚态系统。我们给出了一个简短的调查暗物质模型和凝聚态物质的基础知识,而大部分的审查涉及的理论处理DM-核子和DM-电子相互作用。我们还回顾了最近的实验发展中的探测器技术,并得出结论,展望未来十年的亚GeV DM检测领域。

英文摘要:

Identifying the nature of dark matter (DM) has long been a pressing question for particle physics. In the face of ever-more-powerful exclusions and null results from large-exposure searches for TeV-scale DM interacting with nuclei, a significant amount of attention has shifted to lighter (sub-GeV) DM candidates. Direct detection of the light dark matter in our galaxy by observing DM scattering off a target system requires new approaches compared to prior searches. Lighter DM particles have less available kinetic energy, and achieving a kinematic match between DM and the target mandates the proper treatment of collective excitations in condensed matter systems, such as charged quasiparticles or phonons. In this context, the condensed matter physics of the target material is crucial, necessitating an interdisciplinary approach. In this review, we provide a self-contained introduction to direct detection of keV--GeV DM with condensed matter systems. We give a brief survey of dark matter models and basics of condensed matter, while the bulk of the review deals with the theoretical treatment of DM-nucleon and DM-electron interactions. We also review recent experimental developments in detector technology, and conclude with an outlook for the field of sub-GeV DM detection over the next decade.
