A next-generation liquid xenon observatory for dark matter and neutrino physics

The nature of dark matter and properties of neutrinos are among the most pressing issues in contemporary particle physics. The dual-phase xenon time-projection chamber is the leading technology to cover the available parameter space for weakly interacting massive particles, while featuring extensive sensitivity to many alternative dark matter candidates. These detectors can also study neutrinos through neutrinoless double-beta decay and through a variety of astrophysical sources. A next-generation xenon-based detector will therefore be a true multi-purpose observatory to significantly advance particle physics, nuclear physics, astrophysics, solar physics, and cosmology. This review article presents the science cases for such a detector.

暗物质的本质和中微子的性质是当代粒子物理学中最为紧迫的问题。双相氙时间投影室是覆盖弱相互作用大质量粒子的可用参数空间的领先技术，同时对许多其他暗物质候选者具有广泛的敏感性。这些探测器还可以通过无中微子双β衰变以及各种天体物理源来研究中微子。因此，下一代基于氙的探测器将是一个真正的多用途观测站，能够极大地推动粒子物理学、核物理学、天体物理学、太阳物理学和宇宙学的发展。这篇综述文章介绍了这种探测器的科学依据。
