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可以在大型强子对撞机的Atlas实验中开发，委托和操作新的仪器，这将使新物理学以及对标准模型过程的关键测量进行新颖的搜索。通过将仪器，物理分析和数据密集型计算的专业知识与机器学习和电子设计方面的新思想相结合，它们将使敏感性扩展到开创性的发现。拟议的仪器工作使该小组能够更广泛地对物理研究产生持久影响。该组织还旨在对劳动力发展，K-12教育和增强公共科学素养产生影响。他们将根据小组成员的成功经验，并与最佳实践保持一致，并结合新的计划和活动。这些活动包括一种全面的培训，教育和不断提高科学知识的方法。同时，该小组将以广泛的方法，实验设计，领导力和交流方式培训研究生和博士后研究人员。具体来说，该小组将：（a）进行新物理学的行为搜索，包括轴心般的颗粒，以及对涉及电子（EW）流程（EW）流程和强化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瓷砖量热仪和全球功能提取器（GFEX）量热计触发系统中的作用； （c）提供高光度LHC运行的三个检测器升级4：Atlas Tilecal主板电子设备，量热计全球事件处理器（GEP）触发器和事件过滤器跟踪（EFTRACK）触发系统。芝加哥集团的物理分析活动包括探索Electroweak/Higgs行业；探索黑暗部门；和硬性QCD领域的探索。每个都有可能在粒子物理学中发现和见解的变革性发现。随着ATLAS物理计划和HL-LHC升级计划的进度，该小组将扩大其在多个领域的角色，包括校准，操作和升级瓷砖热量计以及运行3的触发系统，以及升级全球事件处理器（GEP）和事件过滤器触发器系统，以及相关的计算范围，并升级了统计范围。认为值得通过基金会的智力优点和更广泛影响的评论标准来评估值得支持。
