This award funds the research activities of Professor Stephen P. Martin at Northern Illinois University.This project will advance our knowledge of the basic building blocks of matter and the forces of interaction between them. Among the fundamental subatomic particles is the Higgs boson, which was discovered in 2012 and is now the subject of intense studies at the Large Hadron Collider. Professor Martin will pursue an enhanced understanding of the Higgs boson and other subatomic particles. He will also study theories that extend the known particles and forces, including a possibility known as supersymmetry. The central prediction of this theory is that for each of the known types of fundamental particles, there must be another type with very similar properties but which are much heavier. Professor Martin will work on strategies for discovering such new particles at the Large Hadron Collider and proposed future collider experiments. He will also do the same for theories that provide alternatives to supersymmetry. These activities advance the national interest by promoting our understanding of how nature works at the most fundamental level. This project will also have broader impacts. Professor Martin will mentor and train students at both the graduate and undergraduate levels on relevant methods of research. He will also interact directly with pre-college students and other interested members of the public through exhibitions and judging at local and regional science fairs.More technically, Martin will compute multi-loop corrections to the effective potential that governs the scalar field associated with the Higgs boson. He will extend existing results for the effective potential in general non-supersymmetric theories to include supersymmetric models, using regularization methods that respect supersymmetric invariance. He will also develop methods for evaluating three-loop contributions to particle masses, including the Higgs boson and the W and Z bosons of the Standard Model of particle physics. He will study non-minimal theories of supersymmetry, exploring possibilities that address a puzzle called the little hierarchy problem. He will study the production and decay of supersymmetric particles at proposed future proton-proton and electron-positron colliders, to understand the reach of those experiments for making new discoveries. He also plans to continue studies of new particles in non-supersymmetric theories, including, for example, new vector-like leptons.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该奖项用于资助北伊利诺伊大学Stephen P. Martin教授的研究活动。这个项目将推进我们对物质的基本组成部分和它们之间相互作用的力量的认识。在基本的亚原子粒子中，希格斯玻色子是2012年发现的，现在是大型强子对撞机（Large Hadron Collider）密集研究的主题。马丁教授将致力于加深对希格斯玻色子和其他亚原子粒子的理解。他还将研究扩展已知粒子和力的理论，包括一种被称为超对称的可能性。该理论的核心预测是，对于每一种已知类型的基本粒子，必须存在另一种具有非常相似性质但更重的类型。马丁教授将研究在大型强子对撞机上发现这种新粒子的策略，并提出未来的对撞机实验。他还将为提供超对称的替代理论做同样的工作。这些活动促进了我们对自然如何在最基本的层面上运作的理解，从而促进了国家利益。该项目还将产生更广泛的影响。马丁教授将指导和培训研究生和本科生的相关研究方法。他还将直接与大学预科学生和其他感兴趣的公众进行互动，通过展览和在当地和区域科学展览中担任评委。更技术性的是，Martin将计算控制与希格斯玻色子相关的标量场的有效势的多环修正。他将利用尊重超对称不变性的正则化方法，扩展一般非超对称理论中有效势的现有结果，使其包括超对称模型。他还将开发评估粒子质量的三环贡献的方法，包括粒子物理标准模型中的希格斯玻色子和W、Z玻色子。他将研究超对称的非极小理论，探索解决一个被称为小层次问题的难题的可能性。他将在未来的质子-质子和电子-正电子对撞机上研究超对称粒子的产生和衰变，以了解这些实验对新发现的影响。他还计划继续研究非超对称理论中的新粒子，例如，包括新的类矢量轻子。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
