Multidiscipline Approach to the UV Completion of the Standard Model: Astrophysics, Cosmology, and Collider Physics

该奖项资助了纽约州立大学雷曼学院的Luis Ancldoqui教授的研究。经过近20年的规划和建设，大型强子对撞机(LHC)现在是世界上最大、最强大的粒子对撞机。通过基本粒子在高能下相互碰撞，物理学家希望了解物质的基本成分，以及它们在比以往任何时候都更高的能量和更短的距离上的相互作用。目前，解释这些基本粒子如何以尽可能高的能量相互作用的最成功的理论是弦理论。弦理论的优势在于，它不仅可以将所有基本粒子的存在解释为基本弦的不同激发，还可以解释引力如何与其他非引力统一起来。在他的研究中，Ancldoqui教授的目标是开发方法来搜索和测试来自大型强子对撞机弦理论的一些想法。因此，这一领域的研究通过促进科学最基本的方向之一--发现和理解新的物理定律--来促进国家利益。预计该项目还将产生更广泛的重大影响。Ancldoqui教授将让研究生和博士后参与他的研究，从而为开始这一领域研究的初级物理学家提供关键培训。他还打算就他的研究成果进行公开演讲，并根据LHC的结果开发新的课程。更技术上，Ancldoqui教授将考虑扩展标准模型，以D-膜上结束的开放弦为基础，将规范玻色子作为连接到D-膜堆叠上的弦出现，并将手性物质作为交叉D-膜之间延伸的弦出现。假设基本的弦质量标度在TeV范围内，并且理论是弱耦合的，Ancldoqui教授将开发一些搜索策略，这些策略将标志着大型强子对撞机上的弦物理。其中包括对所谓的“格林-施瓦茨机制”的重新审视，对涉及更高规范场的量子场论的作用泛函的修正，使原始作用泛函的量子反常消失，以及对最小左右对称相交D膜模型的研究。他还计划调查，在低质量尺度弦共振的背景下，是否可以解释观察到的和理论计算的介子反常磁矩之间的(可能)差异。安克尔多基教授还将对表现出S-二元性的通胀潜力进行现象学分析。Ancldoqui教授还参与了Pierre Auger的合作，寻找最高能量宇宙射线的起源和性质，并研究质心能量下的粒子相互作用，远远超出大型强子对撞机的能量范围。

This award funds the research of Professor Luis Anchordoqui at CUNY Lehman College.After nearly twenty years of planning and construction, the Large Hadron Collider (LHC) is now the world's largest and most powerful particle collider. By colliding elementary particles against each other at high energies, physicists expect to learn about the fundamental constituents of matter and their interactions at higher energies and smaller distances than have ever been previously explored. Currently the most successful theory for explaining how these elementary particles interact at the highest possible energies is string theory. String theory has the advantage of not only explaining the existence of all of the elementary particles as different excitations of a fundamental string, but also explaining how gravity might be unified with the other, non-gravitational forces. In his research, Professor Anchordoqui aims to develop methods to search for and test some of the ideas coming from string theory at the LHC. As a consequence, research in this area advances the national interest by promoting the progress of science in one of its most fundamental directions: the discovery and understanding of new physical laws. This project is also envisioned to have significant broader impacts. Professor Anchordoqui will involve graduate students and postdocs in his research, and thereby provide critical training for junior physicists beginning research in this field. He also intends to give public lectures on his research results, and develop new course curricula based on results from the LHC.More technically, Professor Anchordoqui will consider extensions of the Standard Model based on open strings ending on D-branes, with gauge bosons emerging as strings attached to stacks of D-branes and with chiral matter emerging as strings stretching between intersecting D-branes. Assuming that the fundamental string mass scale is in the TeV range and the theory is weakly coupled, Professor Anchordoqui will develop a number of search strategies that would signal string physics at the LHC. These include a re-examination of the so-called "Green-Schwarz mechanism", a modification of an action functional of a quantum field theory involving higher gauge fields that makes a quantum anomaly of the original action functional disappear, as well as the study of the minimal left-right symmetric intersecting D-brane model. He also plans to investigate whether the (possible) discrepancy between observation and theoretical calculation of the anomalous magnetic moment of the muon can be explained in the context of low-mass-scale string resonances. Professor Anchordoqui will also undertake a phenomenological analysis of inflationary potentials exhibiting S-duality. Professor Anchordoqui is also involved with the Pierre Auger Collaboration, searching for the origin and nature of the highest-energy cosmic rays and studying particle interactions at center-of-mass energies well beyond those attained at the LHC.
