One of the major intellectual achievements of the 20th century was the development of the Standard Model (SM) of particle physics. This model succeeded in classifying all the elementary particles known at the time into a hierarchy of groups having similar quantum properties. The validity of this model to date was confirmed by the discovery of the Higgs boson at the Large Hadron Collider (LHC). However, the Standard Model as it currently exists leaves open many questions about the universe, including such fundamental questions as to why the Higgs mass has the value it has. One of the primary functions of the Compact Muon Solenoid (CMS) experiment at the LHC, which remains the premier Energy Frontier particle accelerator, operating at the CERN laboratory near Geneva Switzerland, is to discover new physics beyond the Standard Model. This project will analyze the latest data from the CMS experiment looking for signals of beyond the Standard Model. The work that will be accomplished with this award will impact three broad areas: 1) furthering the analysis techniques that might well discover new physics at the LHC 2) Alignment of the new tracking detector upgrade of the CMS detector (HL-LHC) and 3) workforce development and outreach to the broader community.This group led the work on the 4-lepton decay channel in the discovery of the Higgs. This award will expand on analysis techniques developed in that discovery, applying it to the new data that has now been delivered by the LHC and use it in new searches for physics beyond the Standard Model. To discover this new physics, this group will probe the large data sample of Higgs bosons, measuring details such as precision measurements of the Higgs boson mass, width, quantum numbers, Charge Parity properties, and more generally, the tensor structure of Higgs interactions with vector bosons and fermions. The larger dataset now available could yield new sources of symmetry violation (called Charged Parity or CP violation) that might be associated with the Higgs boson. This project will also support technical contributions to the operation of the CMS detector and to the study of new detector technology for high luminosity upgrades of the LHC, the HL-LHC which has now just started. The contributions to the study of detector upgrades are based on tools that were developed to support the present operation. The PI's group is the host of a QuarkNet center that has a current membership of 25 Baltimore area high school teachers. The QuarkNet center has initiated and helped to organize a very successful series of regional Physics Fairs that have brought science to thousands of area residents.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.

20世纪的主要知识成就之一是粒子物理学标准模型（SM）的发展。该模型成功地将当时已知的所有基本粒子分类为具有相似量子特性的组的层次结构。迄今为止，该模型的有效性通过在大型强子对撞机（LHC）中发现希格斯玻色子的发现得到了证实。但是，目前存在的标准模型为宇宙留下了许多问题，包括有关希格斯质量为何具有其价值的基本问题。 LHC紧凑型MUON电磁阀（CMS）实验的主要功能之一，它仍然是在瑞士日内瓦附近的CERN实验室运营的主要能量边界粒子加速器，是发现超出标准模型的新物理学。该项目将分析来自CMS实验的最新数据，以寻找超出标准模型的信号。通过该奖项将完成的工作将影响三个广泛的领域：1）进一步在LHC上发现新物理学的分析技术2）CMS探测器的新跟踪探测器升级（HL-LHC）（HL-LHC）和3）劳动力发展并向更广泛的社区推出。 该奖项将扩展到该发现中开发的分析技术，将其应用于LHC现在已提供的新数据，并将其用于标准模型以外的物理学的新搜索。 为了发现这种新物理学，该组将探测Higgs玻色子的大数据样本，测量细节，例如希格斯玻色子质量的精确测量，宽度，量子数，电荷奇偶校验特性，以及更一般的HIGGS与载体玻色子和效率的张量。现在可用的较大数据集可能会产生与希格斯玻色子有关的新的违反对称性违规来源（称为带电平价或违反CP的违规行为）。该项目还将支持CMS探测器运行的技术贡献，并为HL-LHC的高光度升级（HL-LHC）的高光度升级进行新的检测器技术研究，该技术刚刚开始。对检测器升级研究的贡献是基于为支持当前操作而开发的工具。 PI的小组是一个Quarknet中心的主持人，该中心目前拥有25个巴尔的摩地区高中教师的会员资格。 Quarknet中心已经发起并帮助组织了一系列非常成功的区域物理博览会，这些博览会已将科学带到了数千个地区居民。该奖项反映了NSF的法定任务，并被认为是通过基金会的智力优点和更广泛影响的审查标准通过评估来通过评估来支持的。
