This award will allow the University of Chicago particle physics group to develop, commission, and operate new instrumentation for the ATLAS experiment at the Large Hadron Collider that will enable novel searches for new physics as well as key measurements of Standard Model processes. By combining their expertise in instrumentation, physics analysis, and data-intensive computation with novel ideas in machine learning and electronics design, they will extend sensitivities to groundbreaking discoveries. The proposed instrumentation efforts enable the group to have a long-lasting impact on research in physics more broadly. The group also aims to have an impact on workforce development, K-12 education, and enhanced public scientific literacy. They will incorporate new programs and activities based on group members' successful experiences and alignment with best practices. These activities comprise a comprehensive approach to training, educating, and increasing scientific literacy as they advance scientific knowledge. At the same time, the group will train graduate students and postdoctoral researchers in a broad range of methods, experimental design, leadership, and communication.Specifically, the group will: (a) Conduct searches for new physics, including axion-like particles, and conduct detailed measurements of the Standard Model (SM) involving electroweak (EW) processes and hadronic final states; (b) Continue and strengthen their roles in commissioning and operating the Tile calorimeter and global Feature Extractor (gFEX) calorimeter trigger system; (c) Deliver three detector upgrades for the High Luminosity LHC Run 4: ATLAS TileCal Main Board electronics, the calorimeter Global Event Processor (GEP) trigger, and the Event Filter Tracking (EFTrack) trigger system. The Chicago group's physics analysis activities include exploration of the electroweak/Higgs sector; exploration of the dark sector; and exploration of the hard QCD sector. Each has the potential for transformative discoveries and insights in particle physics. The group will expand its roles in several areas as the ATLAS physics program and the HL-LHC upgrade program progress, including calibrating, operating, and upgrading the Tile Calorimeter and commissioning the trigger system for Run 3, as well as upgrading the Global Event Processor (GEP) and Event Filter Trigger systems, and the associated computing paradigms, for the HL-LHC.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.

该奖项将使芝加哥大学粒子物理小组能够为大型强子对撞机的 ATLAS 实验开发、调试和操作新仪器，从而实现对新物理的新颖搜索以及标准模型过程的关键测量。通过将仪器、物理分析和数据密集型计算方面的专业知识与机器学习和电子设计方面的新颖想法相结合，他们将扩大对突破性发现的敏感性。拟议的仪器工作使该小组能够对更广泛的物理学研究产生持久的影响。该组织还旨在对劳动力发展、K-12 教育和提高公众科学素养产生影响。他们将根据小组成员的成功经验并与最佳实践保持一致，纳入新的计划和活动。这些活动包括在推进科学知识的同时进行培训、教育和提高科学素养的综合方法。同时，该小组还将在广泛的方法、实验设计、领导力和沟通方面培训研究生和博士后研究人员。具体来说，该小组将：（a）进行新物理学的研究，包括轴子状粒子，并对涉及电弱（EW）过程和强子最终状态的标准模型（SM）进行详细测量； (b) 继续并加强其在调试和操作 Tile 量热计和全局特征提取器（gFEX）量热计触发系统方面的作用； (c) 为高亮度 LHC Run 4 提供三个探测器升级：ATLAS TileCal 主板电子器件、热量计全局事件处理器 (GEP) 触发器和事件过滤器跟踪 (EFTrack) 触发系统。芝加哥小组的物理分析活动包括弱电/希格斯领域的探索；探索黑暗领域；以及硬QCD领域的探索。每个人都具有在粒子物理学领域进行变革性发现和见解的潜力。随着 ATLAS 物理计划和 HL-LHC 升级计划的进展，该小组将扩大其在多个领域的作用，包括校准、操作和升级 Tile Calorimeter，调试 Run 3 的触发系统，以及升级 Global Event Processor (GEP) 和事件过滤器触发系统，以及相关的计算范式，用于 HL-LHC。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力优点和更广泛的影响审查进行评估，被认为值得支持 标准。
