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，已经实现了碰撞粒子的最高能量。2012年在大型强子对撞机上观测到了一种独特的基本粒子--希格斯玻色子，开启了粒子物理学发现和理解的新纪元。该奖项资助的小组将致力于粒子物理领域最耐人寻味的公开问题。它通过更详细地研究希格斯玻色子的性质，研究物质的基本组成部分及其相互作用的规律。反映这些基本粒子和相互作用的最好理解的理论-标准模型的预测将受到严格的测试，许多理论家预测的新现象的发现将被许多理论家预测。内布拉斯加州大学林肯分校(UNL)的高能物理小组将在大型强子对撞机的紧凑型Muon螺线管(CMS)实验中进行基本粒子物理研究。该小组将研究希格斯玻色子的性质，以及它如何与顶夸克相互作用。计划对顶夸克的性质和产生截面进行几次测量。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，阐明电弱对称破缺的机制，并可能提供新现象的线索。超对称性是超越标准模型的最有趣的理论之一，搜索它的签名将被执行。在授予期间，UNL HEP小组将完成对CMS Forward Pixel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、软件开发和操作做出重大贡献。

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.
