这个奖项资助了北伊利诺伊大学斯蒂芬·P·马丁教授的研究活动。这个项目将增进我们对物质的基本构件以及它们之间相互作用力的知识。希格斯玻色子是基本的亚原子粒子之一,它于2012年被发现,现在是大型强子对撞机密集研究的对象。马丁教授将加强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。这一理论的中心预测是,对于每一种已知类型的基本粒子,肯定有另一种类型的基本粒子具有非常相似的性质,但质量要大得多。马丁教授将在大型强子对撞机上研究发现这种新粒子的策略,并计划进行未来的对撞机实验。他还将为提供超对称性替代品的理论做同样的事情。这些活动促进了我们对自然如何在最根本层面上运作的理解,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。他还将通过展览和在当地和地区性科学博览会上的评委与大学预科学生和其他感兴趣的公众直接互动。更严格地说,马丁将计算与希格斯玻色子相关的标量场的有效势的多回路修正。他将使用尊重超对称不变性的正则化方法,将一般非超对称理论中的有效势的现有结果扩展到包括超对称模型。他还将开发评估三环对粒子质量贡献的方法,包括粒子物理标准模型的希格斯玻色子和W玻色子和Z玻色子。他将研究超对称的非最小理论,探索解决一个名为小等级问题的谜题的可能性。他将在拟议中的未来质子-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,包括例如新的矢量型轻子。这一奖项反映了NSF的法定使命,并通过使用基金会的智力优势和更广泛的影响审查标准进行评估,被认为值得支持。
英文摘要
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.
