Particle physics is focused on the search for the most basic building blocks of the Universe 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 one of the world's most powerful and sophisticated cameras, observing the collisions of protons and recording the outcomes for detailed study by CMS experimentalists. The members of the high energy physics group at Rutgers University have been crucial to the construction, maintenance, and continued improvement of the device itself. They have initiated and guided several studies of the data collected, including ones that led to the discovery of the Higgs boson in 2012. The data being gathered now and in the coming years will allow a greater understanding of the basic structure of nature, perhaps including insights into the huge difference in the strengths of the fundamental forces, or even glimpses of new fundamental particles. The Rutgers high energy physics group will continue to be at the forefront of these investigations. The Rutgers high energy physics group is carrying out several with the CMS experiment at CERN, studying proton-proton interactions at a center-of-mass energy of 13 TeV. They continue to innovate and implement new data analysis techniques in searches for new physics signatures with leptons, photons, jets and missing energy. They are also incorporating ideas like high-speed pattern recognition, deep multivariate neural networks, self-guided machine learning, and image recognition into the search for new physics at the deepest levels. The group has a history of leadership in CMS, including leading major analysis groups and leading efforts on detector hardware and operations in the areas of tracking, calorimetry and luminosity measurement. They work closely with theorists to bring forth new ideas, leading to a rich program of physics analyses that has originated from their efforts. This award also allows the Rutgers group to continue deploying an improved version of front-end electronics they designed for the pixel detector, as well as testing and installation of the front-end electronics for the forward hadron calorimeter. They are also working on longer-term upgrades, specifically the Outer Tracker and a fast Track Trigger, introducing innovative ideas that promise to increase the reach for new physics to regions not previously capable of being probed by any collider. They plan to host a production and testing facility for the upgrades. Through the Rutgers QuarkNet program, the group runs summer workshops for high-school teachers and students from across New Jersey, analyzing LHC data and building cosmic-ray telescopes. They also mentor undergraduate students from Rutgers and the NSF REU program, as well as qualified high school students. These students work closely with the group and contribute to ongoing studies and physics analyses. To address the underrepresentation of women in STEM fields, they are helping develop programs to provide research opportunities to collegiate and pre-college women. They have developed a highly successful intensive instructional program for high school physics teachers in AP-level physics which has led to improved student understanding of physics, and a marked increase in perfect scores on the AP-physics exam. The Rutgers group continues to convey the excitement of particle physics with frequent talks at local high schools, libraries, and other venues.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.

粒子物理学的重点是寻找宇宙最基本的组成部分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探测器是世界上最强大和最复杂的相机之一，它观察质子的碰撞并记录结果，供CMS实验人员进行详细研究。罗格斯大学高能物理小组的成员对设备本身的建造、维护和持续改进至关重要。他们发起并指导了对收集到的数据的几项研究，包括导致2012年发现希格斯玻色子的研究。现在和未来几年收集的数据将使我们更好地理解自然的基本结构，也许包括对基本力强度的巨大差异的洞察，甚至是对新基本粒子的一瞥。罗格斯大学高能物理小组将继续站在这些研究的最前沿。罗格斯大学高能物理组正在欧洲核子研究中心进行几项CMS实验，研究质心能量为13 TeV的质子-质子相互作用。 他们继续创新和实施新的数据分析技术，以寻找具有轻子，光子，喷流和丢失能量的新物理特征。他们还将高速模式识别、深度多变量神经网络、自引导机器学习和图像识别等想法融入到对最深层次新物理学的探索中。该集团在CMS领域拥有领导地位，包括领导主要分析团队，并在跟踪、量热和光度测量领域的探测器硬件和操作方面发挥主导作用。他们与理论家密切合作，提出新的想法，从而产生了丰富的物理分析计划，这源于他们的努力。 该奖项还允许罗格斯大学继续部署他们为像素探测器设计的前端电子设备的改进版本，以及测试和安装前向强子量能器的前端电子设备。他们还在进行长期升级，特别是外部跟踪器和快速跟踪触发器，引入创新的想法，承诺将新物理学的范围扩大到以前无法被任何对撞机探测的区域。他们计划为升级提供生产和测试设施。通过Rutgers QuarkNet项目，该组织为来自新泽西的高中教师和学生举办暑期研讨会，分析LHC数据并建造宇宙射线望远镜。他们还指导罗格斯大学和NSF REU计划的本科生，以及合格的高中生。这些学生与小组密切合作，并为正在进行的研究和物理分析做出贡献。为了解决妇女在STEM领域代表性不足的问题，他们正在帮助制定计划，为大学和大学预科妇女提供研究机会。他们为高中物理教师开发了一个非常成功的AP级物理强化教学计划，提高了学生对物理的理解，并显着增加了AP物理考试的满分。罗格斯大学的团队继续通过在当地高中，图书馆，该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
