项目摘要

This award supports the base research program of the SuperCDMS SNOLAB experiment that will address one of the most fundamental questions of modern science—the nature of dark matter. SuperCDMS explores a lower mass dark matter parameter space with world-leading sensitivity that is complementary to on-going searches at the Large Hadron Collider, indirect detection experiments, and direct detection experiments like LZ and XENONnT that will search for heavier-mass dark matter. The SuperCDMS SNOLAB experiment will have a broad impact that extends beyond the search for dark matter. The experiment’s phonon-mediated detectors have applications in cosmology, astronomy and industry. This effort will contribute opportunities for training of undergraduate and graduate students and postdoctoral researchers. The SuperCDMS Collaboration has a long history of outreach with a strong focus on engaging students from underrepresented groups at all educational levels. This award will enable the development of accessible analysis resources that will significantly increase the number of undergraduates involved in SuperCDMS science analysis and in particle physics analyses in general. In addition, SuperCDMS will leverage the SNOLAB outreach team by increasing participation in tour groups and SNOLAB on-site exhibits, and partner with the Colegio de F´ısica Fundamental e Interdiciplinaria de las Am´ericas (COFI) in bringing dark matter themed educational efforts to student and public audiences in Puerto Rico.The goal of the SuperCDMS Collaboration is to directly detect galactic dark matter and, in so doing, address the following questions: what is the particle nature of dark matter, what are its astrophysical properties, and how does it relate to the Standard Model? In pursuit of this goal, the Collaboration is in the process of constructing a new experiment, SuperCDMS SNOLAB, equipped with advanced cryogenic detectors that have unprecedented sensitivity to dark matter particles with masses at and below the GeV/c-squared scale, with an ultimate potential sensitivity down to dark matter-nucleon cross sections where solar neutrino-nucleus scattering becomes significant (the so-called “neutrino fog”). The experiment will be sited in SNOLAB, Sudbury, Canada.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项支持SuperCDMS Snolab实验的基础研究计划，该计划将解决现代科学最根本的问题之一，即暗物质的本质。 SuperCDMS探索了较低的质量暗物质参数空间，具有世界领先的灵敏度，该灵敏度可用于大型强子对撞机的持续搜索，间接检测实验，以及直接检测实验（如LZ和Xenonnt），可以搜索重质量的质量质量暗物质。 SuperCDMS Snolab实验将产生广泛的影响，超出了对暗物质的搜索。该实验的声子介导的探测器在宇宙学，天文学和工业中都有应用。这项努力将为培训本科生和研究生和博士后研究人员提供帮助。 SuperCDMS的合作有着悠久的宣传历史，重点是吸引来自所有教育水平的代表性不足小组的学生。该奖项将使可访问的分析资源的发展能够大大增加超级科学分析和粒子物理分析中涉及的大学生的数量。此外，SuperCDMS将通过增加参与巡回赛和Snolab现场展览的参与并与Colegio de f´isica的基本互动e las am'ericas（COFI）与Colegio de f´isica的基本互动合作来利用Snolab外展团队，并与Puertoct of Puertoction the Supperct the Supperc the Supperc the Supperc the Supperc the Supperc the Supperc.在这样做时，解决以下问题：暗物质的粒子性质是什么，其天体物理特性是什么？它与标准模型有何关系？ In pursuit of this goal, the Collaboration is in the process of constructing a new experiment, SuperCDMS SNOLAB, equipped with advanced cryogenic detectors that have unprecedented sensitivity to dark matter particles with masses at and below the GeV/c-squared scale, with an ultimate potential sensitivity down to dark matter-nucleon cross sections where solar neuron-nucleus scattering becomes significant (the so-called “neutrino 多雾路段”）。该实验将位于加拿大萨德伯里（Sudbury）的斯诺拉布（Snolab）。该奖项反映了NSF的法定任务，并通过使用基金会的知识分子优点和更广泛的影响审查标准来评估，被认为是珍贵的支持。
