This award funds the research activities of Professor Stephen P. Martin at Northern Illinois University. This project will advance our knowledge of how the basic building blocks of nature interact. This includes enhanced understanding of the known fundamental subatomic particles, including the Higgs boson discovered in 2012. Martin will also study theories that go beyond the known fundamental sub-atomic particles, including a possibility known as supersymmetry. The key prediction of supersymmetry is that for each of the known fundamental particle types, there must be a "partner" with very similar properties but a much larger mass. Martin will work on strategies for discovering these new particles in experiments including the Large Hadron Collider and proposed future colliders, and will do the same for theories that provide alternatives to supersymmetry. As a result, support for this proposal advances the national interest by promoting the progress of science in one of its most fundamental directions: the discovery and understanding of new physical law. Martin will also mentor students at both the graduate and undergraduate levels on research methods, participate in the education and training of high-school teachers, and interact directly with pre-college students through judging at local and regional science fairs.More technically, the proposed research will study the equations that relate the underlying parameters of the Standard Model and the quantities measured at colliders. This will be accomplished by performing relevant calculations in a more accurate and detailed approximation than ever before. These calculations, together with more accurate data on the Higgs boson that will be obtained by the Large Hadron Collider, will allow us to quantitatively understand the dynamics of the Higgs field and test the consistency of the minimal Standard Model of particle physics. Martin will study and improve formulas relating the masses of the Higgs boson and other particles to the Higgs self-interaction strength and its interactions with other particles. Martin will also continue to study supersymmetry, which now is significantly constrained, but certainly not ruled out, by Large Hadron Collider data. Martin will work on strategies for maximizing the experimental reach of the Large Hadron Collider for new particles, by investigating novel signatures and areas of parameter space where discovery or exclusion might be particularly difficult or subtle. Martin will develop more accurate calculations and theoretical tools that will aid in the interpretation and understanding of a future discovery of supersymmetry or new stronger limits on supersymmetry, by relating the masses and interactions of the new particles to the parameters of the underlying theory. This research will affect the interpretation of experiments at the CERN LHC proton-proton collider as well as a variety of dark matter detection experiments. These experiments are major science infrastructures, and employ many researchers and students at all levels in several different science and engineering fields.

该奖项为北伊利诺伊大学的斯蒂芬·马丁教授的研究活动提供资金。该项目将促进我们对自然基本构件如何相互作用的了解。 这包括对已知基本亚原子颗粒的了解，包括2012年发现的希格斯玻色子。 超对称性的关键预测是，对于每种已知的基本粒子类型，必须有一个非常相似的属性但质量更大的“伴侣”。 马丁将采用在包括大型强子对撞机和拟议的未来山液在内的实验中发现这些新颗粒的策略，并将对提供超对称性替代方案的理论也做同样的事情。 结果，对该提案的支持通过以其最根本的方向之一来促进科学的进步来提高国家利益：对新物理法的发现和理解。 马丁还将指导研究生和本科生的研究方法，以研究方法的研究，参加高中教师的教育和培训，并通过在当地和区域科学博览会上进行评判直接与预科学生进行互动。从技术上讲，拟议的研究将研究与标准模型的基础模型和数量相关的方程式。 这将通过比以往任何时候都更准确，更详细的近似来完成相关计算来实现。 这些计算以及大型强子对撞机将获得的希格斯玻色子的更准确的数据将使我们能够定量了解希格斯场的动力学并测试粒子物理学最小标准模型的一致性。 马丁将研究和改进将希格斯玻色子和其他颗粒质量与希格斯自我交互强度及其与其他颗粒相互作用的公式。 马丁还将继续研究超对称性，现在，大型强子对撞机数据现在受到了显着限制，但肯定不会排除。 马丁将通过调查发现或排除可能特别困难或微妙的参数空间区域，以最大程度地提高策略，以最大程度地提高大型强子对撞机的实验覆盖范围。 马丁将开发更准确的计算和理论工具，这些工具将通过将新粒子的质量和相互作用与基础理论的参数联系起来，从而有助于解释和理解超对称性或对超对称性的新的更强限制。 这项研究将影响CERN LHC Proton-Proton对撞机以及各种暗物质检测实验的实验的解释。 这些实验是主要的科学基础设施，并在几个不同的科学和工程领域雇用了许多研究人员和学生。
