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. 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 early data analysis and final R&D in preparation for 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: analyzing the nearly 150/fb of data collected during the past run, preparing for and then beginning to analyze twice as much data from the next run, and finalizing the plans 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 has also taken on 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 eleven different experimental programs at seven 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界最基本的构建块以及约束它们的规则。位于瑞士日内瓦附近的欧洲核子研究中心大型强子对撞机（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。 大型强子对撞机上的CMS探测器是一台功能强大、精密的相机，可以观察质子的碰撞，并记录下副产品，供CMS实验人员进行详细研究。通过这个项目，圣母大学的高能物理组将通过为下一次LHC运行的数据分析、准备和操作以及早期数据分析和最终研发做出贡献，最大限度地发挥CMS实验的发现潜力，为LHC的高光度升级做准备。接下来的三年将是一个充满挑战的时期，因为CMS实验在三个不同的方面向前推进：分析在过去运行期间收集的近150/fb的数据，准备并开始分析下一次运行的两倍数据，以及最终确定计划并开始建设高光度LHC升级。Notre Dame的活动包括CMS探测器的几个领域，包括电磁量热计，强子量热计，触发器，计算和离线软件。他们的物理分析计划利用了过去对希格斯和顶夸克物理学的投资，同时也为直接和间接探索新物理学建立了新的方向。圣母大学小组将继续利用他们在量热法方面的专业知识进行几次希格斯分析，并寻找新的现象，包括希格斯衰变为两个τ轻子，两个光子，或一个μ轻子和一个τ轻子。此外，他们将利用他们对CMS量热法第一阶段升级的贡献，在下一次LHC运行期间提高性能。他们还将继续协调和管理Endcap和Barrel Hadron Calorimetry的光学读出和解码。该小组还在高亮度大型强子对撞机升级项目中发挥了领导作用，包括电磁和强子桶量热计升级、端盖量热计升级以及为CMS添加新的定时层探测器。该项目还包括对Level 1 Track Trigger升级的贡献，以及对High Level Trigger操作、离线和计算以及数据保存的持续贡献。该小组将通过QuarkNet和许多其他面向公众的举措广泛参与教育和推广。 Notre Dame是QuarkNet的领导和管理机构，QuarkNet目前由25个州和波多黎各的52个中心组成，并已扩展到包括7个国家和外国实验室的11个不同的实验项目。他们的推广工作包括开发和实施LHC数据和宇宙射线数据的电子实验室（e-Labs），基于粒子物理学和天体物理学的大师班，以及参与支持本科生，高中教师和高中学生暑期研究的计划。通过这些努力，他们继续开发和建立一套外展材料和示范项目，在多个层面上向公众介绍粒子物理学，从教室里对LHC希格斯数据的真实的物理分析到史密森尼的粒子探测器展示。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的评估被认为值得支持。影响审查标准。
