This award funds the research activities of Professor Alakabha Datta at the University of Mississippi. One of the main goals of particle physics research is to test our present understanding of the fundamental constituents of matter and their interactions through very high precision experiments. In the process, physicists hope to find the limit at which our present theories break down and have to be replaced by new physical laws. In the future, it is possible that these new laws will be exploited to develop novel technologies. As a result, this kind of research advances the national interest not only by increasing our understanding of how nature works at the most fundamental level but also potentially by providing solutions to the nation's technological needs over the long term. As part of his research, Professor Datta will analyze data from various ongoing experimental facilities in order to rigorously test our present understanding of fundamental physics, as encapsulated within the so-called Standard Model. Professor Datta will also test various models of new physics beyond the Standard Model with data from different high precision experiments. This project will also have significant broader impacts. It will provide education and training to a graduate student. In particular, the graduate student will learn new research techniques and also learn to effectively communicate their research results via written publications and oral presentations. Professor Datta and his student will also give lectures on their research results at various research institutions and in public forums. Finally, Professor Datta will develop special courses on the new developments in the field based on his research.At a technical level, Professor Datta and his group will explore clean ways to look for physics beyond the Standard Model of particle physics in various precision flavor experiments. With the historic discovery of a new particle, the Higgs boson, by the Large Hadron Collider experiment, it is expected that many new particles may be found in the near future. Information on the couplings and other properties of these particles can be indirectly obtained from precision measurements in low energy flavor experiments. It is also likely that new physics not easily accessible at high-energy collider experiments may be probed by analyzing data from precision flavor physics measurements at low energies.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.

该奖项资助密西西比大学Alakabha Datta教授的研究活动。粒子物理学研究的主要目标之一是通过非常高精度的实验来检验我们目前对物质基本成分及其相互作用的理解。在这个过程中，物理学家希望找到我们目前的理论崩溃的极限，并且必须被新的物理定律所取代。在未来，这些新定律有可能被用来开发新技术。因此，这种研究不仅增加了我们对自然如何在最基本的层面上运作的理解，而且还可能为国家的长期技术需求提供解决方案，从而促进了国家利益。作为他研究的一部分，达塔教授将分析来自各种正在进行的实验设施的数据，以严格检验我们目前对基础物理学的理解，这些理解被封装在所谓的标准模型中。达塔教授还将用来自不同高精度实验的数据，测试标准模型之外的各种新物理模型。该项目还将产生更广泛的重大影响。它将为研究生提供教育和培训。特别是，研究生将学习新的研究技术，并学会通过书面出版物和口头报告有效地交流他们的研究成果。达塔教授和他的学生还将在不同的研究机构和公共论坛上演讲他们的研究成果。最后，Datta教授将在他的研究基础上开发关于该领域新发展的专门课程。在技术层面上，达塔教授和他的团队将在各种精确的风味实验中探索寻找粒子物理标准模型之外的物理的干净方法。随着大型强子对撞机实验历史性地发现了一种新粒子——希格斯玻色子，人们预计在不久的将来会发现许多新粒子。通过低能风味实验的精确测量，可以间接获得这些粒子的耦合和其他性质的信息。在高能对撞机实验中不容易获得的新物理也可能通过分析低能下精确风味物理测量的数据来探测。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。
