论文摘要
直接使用敏感地下探测器来检测暗物质是解决什么是暗物质问题的最有希望的方法之一。下一代地下实验将在两个方向上搜索暗物质。一种是使用较大的目标质量探测器进一步探测WIMP参数空间中较小的横截面，而另一个是探测较低的质量暗物质，这需要具有极低阈值的新技术。一旦检测到暗物质，就需要进行方向敏感性和更长的暴露量和较大目标质量的实验来验证其宇宙起源并进一步研究其性质。该报告涵盖了地下设施对下一代暗物质搜索实验的需求，该实验具有高贵的液体，低温验证仪和其他技术。
Detecting dark matter directly using sensitive underground detectors is one of the most promising ways to address the question of what is dark matter. The next generation underground experiments will search for dark matter in two directions. One is to use larger target mass detectors to further probe smaller cross sections in the WIMP parameter space and the other is to probe lower mass dark matter which requires new technologies with extremely low threshold. Once dark matter is detected, experiments with directional sensitivities and experiments with longer exposure and larger target masses are needed for the time-dependent signatures, such as annual modulations, to verify their cosmic origin and to further study their properties. This report covers the underground facilities need for the next generation dark matter search experiments with noble liquids, cryogenic bolometers and other technologies.
