项目摘要

This award funds the research activities of Professor Peisi Huang at the University of Nebraska-Lincoln. The Large Hadron Collider is a vast underground machine that scatters beams of protons against each other to study the fundamental constituents of matter, known as elementary particles. Given huge amounts of data from the Large Hadron Collider and generations of colliders before it, we currently have a fairly robust understanding of the elementary particles and the forces between them --- knowledge encapsulated within the so-called Standard Model of particle physics. However, there is overwhelming evidence that there is new physics beyond the Standard Model. Professor Huang's research aims to utilize the current and future experimental probes to advance our understanding of this new physics. As such, Professor Huang's research 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. The proposed research will provide training opportunities for a diverse group of graduate and undergraduate students. Professor Huang will also aim to increase participation in STEM by making a special effort to involve women, other underrepresented minorities, and first-generation college students. More technically, the proposed research will involve theoretical calculations and utilize data from ongoing experimental programs, including the Large Hadron Collider and Gravitational Interferometers, to advance understanding of fundamental physics beyond the current paradigm. First, Dr. Huang will investigate how to maximize the discovery potential of the Large Hadron Collider, with a focus on Higgs physics. Second, Dr. Huang will leverage gravitational wave observatories to probe new physics beyond the Standard Model, focusing on establishing a connection between gravitational wave physics and flavor physics. Third, Dr. Huang will build new physics models to address the matter-antimatter asymmetry in the universe.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.

该奖项资助了内布拉斯加大学林肯分校黄培思教授的研究活动。大型强子对撞机是一个巨大的地下机器，它将质子束相互散射，以研究物质的基本成分，即基本粒子。考虑到大型强子对撞机和之前几代对撞机的大量数据，我们目前对基本粒子及其之间的力有了相当强大的理解--这些知识封装在所谓的粒子物理学标准模型中。然而，有压倒性的证据表明，在标准模型之外存在着新的物理学。黄教授的研究旨在利用当前和未来的实验探测器来促进我们对这一新物理的理解。因此，黄教授的研究通过促进科学在其最基本的方向之一的进步来促进国家利益：发现和理解新的物理定律。预计该项目还将产生更广泛的重大影响。拟议的研究将为不同群体的研究生和本科生提供培训机会。黄教授还将致力于通过特别努力让妇女、其他代表性不足的少数民族和第一代大学生参与进来，以提高STEM的参与度。从技术上讲，拟议的研究将涉及理论计算，并利用正在进行的实验项目（包括大型强子对撞机和引力干涉仪）的数据，以推动对基础物理学的理解超越当前的范式。首先，黄博士将研究如何最大限度地发挥大型强子对撞机的发现潜力，重点是希格斯物理。其次，黄博士将利用引力波天文台探索标准模型之外的新物理，重点是建立引力波物理和风味物理之间的联系。第三，黄博士将建立新的物理模型，以解决宇宙中的物质-反物质不对称性问题。该奖项反映了NSF的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
