Particle physics focuses on understanding the most basic building blocks of Nature and the rules that bind them. The CERN Large Hadron Collider (LHC), located near Geneva, Switzerland is the world's most powerful particle accelerator, able to reach the highest particle energies in a laboratory setting. The CMS detector at the LHC is a powerful and sophisticated camera, observing the collisions of protons and recording the byproducts for detailed study by CMS experimentalists. One of their primary objectives was to find the Higgs Boson, the last particle in the historically successful "Standard Model" (SM) that accounts for so much of the existence of, and forces between, known particles forming the matter in the universe. This effort has been successful. The next step in the experiments is to look for evidence for physics Beyond the Standard Model (BSM) that might, for instance, account for the presence of the mysterious "Dark Matter" that makes up so much of the mass of the universe. The LHC is currently in the onset of Run 3 with significantly increased event samples. It is possible that evidence for BSM physics could emerge at this higher energy and with the higher event statistics. Through this project, the high energy physics group at Notre Dame University will maximize the discovery potential of the CMS experiment through contributions to data analysis, preparations and operations for the next LHC run as well as data analysis and major contributions to the high luminosity upgrades of the LHC. The next three years will be a challenging period as the CMS experiment presses forward on three separate fronts: continuing the analysis of the data collected during the past run, preparing for and then beginning to analyze twice as much data from the upcoming run, and beginning the construction for the high luminosity LHC upgrades. Notre Dame activities include contributions across several areas of the CMS detector including the electromagnetic calorimeter, the hadronic calorimeter, trigger, computing, and offline software. Their physics analysis plans leverage past investments in Higgs and top quark physics, while also establishing new directions for directly and indirectly probing for new physics. The Notre Dame group will continue to leverage their expertise in calorimetry in several Higgs analyses and searches for new phenomena, including Higgs decays to two tau leptons, two photons, or a muon lepton and a tau lepton. Additionally, they will exploit their contributions to the Phase 1 upgrades of CMS calorimetry for improved performance during the next LHC run. They will also continue to coordinate and manage the optical readout and decoding for Endcap and Barrel Hadron Calorimetry. The group have leadership roles in high-luminosity LHC upgrade projects, including the electromagnetic and hadronic barrel calorimeter upgrades, the endcap calorimeter upgrade, and the addition of a new timing layer detector for CMS. This project also includes contributions to the Level 1 Track Trigger upgrade and continuing contributions to High Level Trigger operations, Offline and Computing, and Data Preservation. The group will engage broadly in Education and Outreach through QuarkNet and many other public-facing initiatives. Notre Dame is lead and the managing institution of QuarkNet, which currently consists of 52 Centers in 25 States and Puerto Rico and has been expanded to include experimental programs at national and foreign laboratories. Their outreach efforts include development and implementation of electronic laboratories (e-Labs) for LHC data and Cosmic Ray Data, Masterclasses based on particle physics and astrophysics, and participation in programs that support summer research for undergraduates, high school teachers and high school students. Through these efforts, they continue to develop and build upon a suite of outreach materials and demonstration projects that bring particle physics to the public on a number of levels, from real physics analysis on LHC Higgs data in the classroom to a particle detector display at the Smithsonian.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.

粒子物理学专注于理解自然的最基本构建块及其绑定它们的规则。位于瑞士日内瓦附近的CERN大型强子对撞机（LHC）是世界上最强大的粒子加速器，能够在实验室环境中达到最高的粒子能量。 LHC上的CMS检测器是一款功能强大且复杂的相机，观察质子的碰撞并记录副产品，以供CMS实验者详细研究。他们的主要目标之一是找到Higgs Boson，这是历史上成功的“标准模型”（SM）中的最后一个粒子，该粒子构成了已知粒子在宇宙中形成物质的已知粒子之间的大部分和力。这项工作已经成功。实验的下一步是寻找超越标准模型（BSM）的物理学的证据，例如，这可能解释了构成宇宙质量大部分的神秘“暗物质”的存在。 LHC目前正在运行3的发作中，事件样本显着增加。 BSM物理学的证据可能会出现在这种较高的能量和较高的事件统计数据下。通过这个项目，巴黎圣母院的高能量物理小组将通过对下一次LHC运行的数据分析，准备和操作以及对LHC高亮度升级的主要贡献的数据分析，准备和操作的贡献，从而最大程度地提高CMS实验的发现潜力。随着CMS实验在三个单独的方面向前推进：继续对过去运行中收集的数据进行分析，准备并开始分析即将到来的运行中的两倍数据，并开始建造高亮度LHC LHC升级的构建，这将是一个具有挑战性的时期：继续对收集的数据进行分析。巴黎圣母院的活动包括在CMS探测器的几个区域中的贡献，包括电磁训练表，强烈量热计，触发，计算和离线软件。他们的物理分析计划利用过去对希格斯和顶级夸克物理学的投资，同时还建立了直接和间接探索新物理学的新方向。巴黎圣母院将继续在几个Higgs分析中利用其在量热法方面的专业知识，并寻找新现象，包括Higgs衰减到两个Tau Leptons，两个光子或一个Muon Lepton和一个Tau Lepton。此外，他们将利用对CMS量热法升级的贡献，以提高下一次LHC运行的性能。他们还将继续协调和管理端盖和桶形强子量载量的光学读数和解码。该小组在高亮度LHC升级项目中扮演着领导角色，包括电磁和辐射枪管热量表升级，端盖热量仪升级以及CMS的新定时层检测器的添加。该项目还包括对1级轨道触发升级的贡献，以及对高级触发操作，离线和计算以及数据保存的持续贡献。该组织将通过Quarknet和许多其他面向公共的计划在教育和宣传中广泛参与。巴黎圣母院（Notre Dame）是领导者，Quarknet的管理机构目前由25个州和波多黎各的52个中心组成，并已扩大到包括国家和外国实验室的实验计划。他们的推广工作包括用于LHC数据和宇宙射线数据的电子实验室（E-LABS）的开发和实施，基于粒子物理和天体物理学的大师班以及参与支持本科生，高中教师和高中生的夏季研究的计划。通过这些努力，他们继续发展并建立在一系列外展材料和演示项目上，这些项目将粒子物理学在教室中的LHC HIGGS数据上进行的实际物理分析到史密森尼的粒子探测器展示。该奖项反映了NSF的法定任务，并通过评估了基金会的范围，并反映了NSF的法定任务，并经过评估。
