项目摘要

The Large Hadron Collider (LHC) is one of the premier scientific instruments of our time. It is the world's largest particle accelerator and has achieved the highest energy of the colliding particles. The observation of a unique fundamental particle, the Higgs boson, at the LHC in 2012 has opened a new era of discovery and understanding in particle physics. The group funded by this award will work on the most intriguing open questions of the field of particle physics. which studies elementary building blocks of matter and laws governing their interactions, by studying in greater detail the properties of the Higgs boson. The predictions of the theory that reflects the best understanding of these fundamental particles and interactions, the Standard Model, will be subject to stringent tests, and discoveries of new phenomena, predicted at the LHC energies by many theorists, are anticipated.The High Energy Physics (HEP) group at the University of Nebraska-Lincoln (UNL) will pursue fundamental particle physics research within the Compact Muon Solenoid (CMS) experiment at the LHC. The group will investigate properties of the Higgs boson and how it interacts with the top quark. Several measurements of top-quark properties and production cross sections are planned. Studies of single and multiple vector boson production will contribute to understanding of the structure of protons, clarify the mechanism of electroweak symmetry breaking, and may provide hints of new phenomena. Searches for signatures of one of the most interesting theories that go beyond the Standard Model, Supersymmetry, will be performed. During the award period, the UNL HEP group will complete its contribution to the manufacturing, installation and commissioning of the Phase 1 upgrade of the CMS Forward Pixel Detector, and will engage in the development of the Phase 2 upgrade of this detector. The group will continue making major contributions to computing, software development, and operations of the CMS experiment.

大型强子对撞机 (LHC) 是我们这个时代最重要的科学仪器之一。它是世界上最大的粒子加速器，并实现了粒子碰撞的最高能量。 2012 年，大型强子对撞机对一种独特的基本粒子希格斯玻色子的观测开启了粒子物理学发现和理解的新时代。该奖项资助的小组将致力于研究粒子物理领域最有趣的开放性问题。通过更详细地研究希格斯玻色子的特性，研究物质的基本组成部分和控制它们相互作用的定律。反映对这些基本粒子和相互作用的最佳理解的理论的预测，即标准模型，将受到严格的测试，并且预计会发现许多理论家在大型强子对撞机能量上预测的新现象。高能物理内布拉斯加大学林肯分校 (UNL) 的 HEP 小组将在大型强子对撞机的紧凑型介子螺线管 (CMS) 实验中进行基础粒子物理研究。该小组将研究希格斯玻色子的特性以及它如何与顶夸克相互作用。计划对顶夸克特性和生产截面进行多次测量。对单矢量和多矢量玻色子产生的研究将有助于理解质子的结构，阐明电弱对称性破缺的机制，并可能提供新现象的线索。将搜索超越标准模型的最有趣的理论之一——超对称的签名。在授标期间，UNL HEP小组将完成对CMS前向像素探测器第一阶段升级的制造、安装和调试的贡献，并将参与该探测器第二阶段升级的开发。该小组将继续为 CMS 实验的计算、软件开发和运营做出重大贡献。
