The Large Hadron Collider (LHC) at CERN in Geneva Switzerland is the world's premier particle collider facility in operation. The Compact Muon Solenoid (CMS) experiment is one of two large experiments at the LHC seeking to understand the nature of the Higgs Boson, which was discovered there in 2012, and to look for evidence of new physics beyond the Standard Model of Particle Physics. These goals are relevant to the understanding of the Universe at its most fundamental level. Meeting this challenge requires the development of new theories, new instrumentation, new accelerators, and new computing and data analysis tools, all of which have significant broader impact for the development of the scientific workforce and the advancement of society. The next three years represent a transition of the LHC physics program from a collision energy of 8 Teraelectronvolts (TeV) data-taking and operation, to extended operations and data-taking at nearly double the energy, 13-14 TeV. Over a thousand scientists from the United States are involved with this scientific program on several major experiments.This award provides support for Dr. Dominguez at the University of Nebraska and his collaborators at eight U.S. universities to upgrade the CMS detector so that it can continue to operate efficiently at higher energies for a longer time and at a higher rate. This upgrade will enable scientists to collect data to search for new physics to explain inconsistencies in the particle theory, which arise as the energy is increased, and to fully understand how the Higgs boson fits into a fundamental theory of the universe. The universities supported by this funding will build new instrumentation to be installed in the CMS detector, which is necessary in order to carry out a real-time selection and collection of data, provide a better measurement of particle energies, and provide charged-particle track information in this new energy and data rate regime. Undergraduate and graduate students will help the postdoctoral researchers and senior scientists build these upgraded detectors, which contain state-of-the-art components. High school students and teachers will also participate in these activities through the QuarkNet program with the goal of attracting and training a new generation of scientists and engineers.

位于瑞士日内瓦欧洲核子研究中心的大型强子对撞机 (LHC) 是世界上运行中的首屈一指的粒子对撞机设施。紧凑介子螺线管 (CMS) 实验是大型强子对撞机的两个大型实验之一，旨在了解 2012 年在那里发现的希格斯玻色子的本​​质，并寻找超越粒子物理学标准模型的新物理学的证据。这些目标与对宇宙最基本层面的理解相关。应对这一挑战需要开发新理论、新仪器、新加速器以及新计算和数据分析工具，所有这些都对科学劳动力的发展和社会的进步产生更广泛的影响。未来三年，LHC 物理计划将从 8 太电子伏 (TeV) 的碰撞能量数据采集和操作，过渡到近两倍能量（13-14 TeV）的扩展操作和数据采集。来自美国的一千多名科学家参与了这一科学计划的多项重大实验。该奖项为内布拉斯加大学的 Dominguez 博士及其在美国八所大学的合作者提供支持，以升级 CMS 探测器，使其能够在更高的能量下持续更长时间、以更高的速率高效运行。这一升级将使科学家能够收集数据来寻找新的物理学，以解释粒子理论中随着能量增加而出现的不一致之处，并充分理解希格斯玻色子如何融入宇宙的基本理论。 受这笔资金支持的大学将建造安装在 CMS 探测器中的新仪器，这对于实时选择和收集数据、提供更好的粒子能量测量以及在新的能量和数据速率机制中提供带电粒子轨迹信息是必要的。 本科生和研究生将帮助博士后研究人员和资深科学家构建这些升级的探测器，其中包含最先进的组件。 高中生和教师也将通过 QuarkNet 计划参与这些活动，目的是吸引和培养新一代科学家和工程师。
