Building for Future Discoveries: Instrumentation, Algorithms, and Training for Physics with the ATLAS Experiment

芝加哥大学粒子物理小组将为大型强子对撞机的ATLAS实验开发、调试和操作新的仪器，这将使新物理学的新颖搜索以及标准模型过程的关键测量成为可能。 通过将他们在仪器仪表，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，他们将扩展对突破性发现的敏感性。该小组将：（a）对涉及电弱过程和强子末态的标准模型进行新的物理研究和详细测量;（B）扩大它们在试运行和操作瓦量能器和全球特征提取量能器触发系统方面的作用;（c）对高亮度大型强子对撞机运行4进行三次探测器升级：瓦式量热计主板电子器件、量热计全局事件处理器（GEP）和硬件跟踪触发器（HTT）系统。芝加哥小组的物理分析活动包括电弱/希格斯区的探索;暗区的探索;以及对硬QCD扇区的探索。每一个都有可能在粒子物理学中产生革命性的发现和见解。随着ATLAS物理计划和HL-LHC升级计划的进展，该小组将扩大其在几个领域的作用，包括校准，操作和升级Tile Calorimeter并调试运行3的触发系统，以及升级全局事件处理器（GEP）和硬件跟踪触发器（HTT）触发系统，以及相关的计算范例。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。该小组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和最佳做法纳入新的方案和活动。这些活动包括一个全面的方法来培训，教育和提高科学素养，因为他们推进科学知识。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。

The University of Chicago particle physics group will 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 group will: (a) Conduct searches for new physics and detailed measurements of the Standard Model (SM) involving electroweak (EW) processes and hadronic final states; (b) Expand their roles in commissioning and operating the Tile calorimeter and global Feature Extractor (gFEX) calorimeter trigger system; (c) Undertake three detector upgrades for the High Luminosity LHC Run 4: Tile Calorimeter Main Board electronics, the calorimeter Global Event Processor (GEP), and the Hardware Track Trigger (HTT) systems.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 Hardware Track Trigger (HTT) trigger systems, and the associated computing paradigms, for the HL-LHC.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.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.
