This award funds the research activities of Professor Stephen P. Martin at Northern Illinois University. These research activities will advance our knowledge of how the basic building blocks of the universe interact. This includes study of the known fundamental subatomic particles, including the recently discovered Higgs boson. Martin will also investigate new theories that go beyond the known 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 another type with very similar properties but much heavier particles than the presently known ones. Martin will work on strategies for discovering these new particles in experiments. Martin will mentor students at both the undergraduate and graduate levels on research methods, participate in education and training of high school teachers, and directly interact with pre-college students through local and regional science fair judging.The proposed research will study the relations between observable quantities measured at colliders and the underlying parameters of the Standard Model, 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 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 Higgs boson mass to its 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 supersymmetric particles, by investigating novel signatures and areas of parameter space where discovery or exclusion will be particularly difficult or subtle. He also plans to investigate variations of the minimal supersymmetric theory that make distinctive predictions that can be experimentally tested if supersymmetric particles are discovered. Martin will develop more accurate calculations and tools that will aid in the interpretation and understanding of a future discovery of 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, and various dark matter detection experiments. These experiments are major science infrastructures, and employ many researchers and students at all levels in a variety of science and engineering fields.

该奖项资助北方伊利诺伊大学斯蒂芬·P·马丁教授的研究活动。这些研究活动将增进我们对宇宙基本组成部分如何相互作用的认识。这包括对已知的基本亚原子粒子的研究，包括最近发现的希格斯玻色子。马丁还将研究超越已知亚原子粒子的新理论，包括被称为超对称的可能性。超对称性的关键预言是，对于每一种已知的基本粒子类型，都必须有另一种具有非常相似性质的粒子，但比目前已知的粒子重得多。马丁将致力于在实验中发现这些新粒子的策略。马丁将指导本科生和研究生的研究方法，参与高中教师的教育和培训，并通过当地和地区科学博览会的评审与大学预科生直接互动。拟议的研究将研究在对撞机上测量的可观测量与标准模型的基本参数之间的关系，通过比以往任何时候都更精确和详细的近似执行相关计算。这些计算，再加上大型强子对撞机将获得的关于希格斯玻色子的更精确的数据，将使我们能够理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。马丁将研究和改进希格斯玻色子质量与其自相互作用强度及其与其他粒子相互作用的公式。马丁还将继续研究超对称性，它现在受到大型强子对撞机数据的显著限制，但肯定不会被排除在外。马丁将致力于最大限度地提高大型强子对撞机对超对称粒子的实验范围的策略，通过研究新的签名和参数空间的领域，发现或排除将特别困难或微妙。他还计划研究最小超对称理论的变体，这些变体可以做出独特的预测，如果发现超对称粒子，这些预测可以通过实验进行验证。马丁将开发更精确的计算和工具，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，帮助解释和理解未来发现的超对称性。这项研究将影响欧洲核子研究中心LHC质子-质子对撞机实验的解释，以及各种暗物质探测实验。这些实验是主要的科学基础设施，并雇用了许多研究人员和学生在各个层次的各种科学和工程领域。
