项目摘要

This award funds the research activities of Professors Pran Nath, James Halverson, Brent D. Nelson, and Tomasz R. Taylor at Northeastern University. Under this grant, research will be conducted across a wide range of topics in theoretical high-energy physics. These topics include many of the most exciting current research areas ranging from a unique kind of symmetry amongst the elementary particles called "supersymmetry" to speculative theories that might be able to unify quantum mechanics and gravity, such as string theory and F-theory, and studies of new ways of studying the behavior of particles when they scatter --- methods involving so-called "celestial amplitudes". In addition, machine-learning tools will be used to explore the nature of fundamental physics beyond the Standard Model. New data expected to emerge from RUN3 of the Large Hadron Collider (LHC) and from a variety of astrophysical experiments will also be explored for evidence of new physics beyond the Standard Model of electroweak and strong interactions. This research will advance the national interest by advancing fundamental physics at the frontiers of current knowledge within the United States. These research projects will also involve several Ph.D. students working under the guidance of the PIs. In addition, an important part of this project is the outreach program TheoryNet, which fosters direct interactions between Boston-area theorists and high-school students through lecture presentations and demonstrations.More technically, the research to be performed is aimed at developing new formalisms and tools to investigate the nature of physics beyond energy scales currently accessible. This includes theoretical work related to unified models based on strings and F-theory and further investigations on celestial amplitudes. This work also includes the development of methods to find possible evidence of supersymmetry or strings in new data expected to emerge from the LHC. This project will also include the application of machine learning for the exploration of the string landscape and related phenomena. This project will also include work at the interface of particle theory and cosmology, including a more unified framework encompassing dark matter and dark energy. Another area of investigation includes the study of hidden sectors which appear in a broad class of supergravity and string models and which have begun to play an increasingly significant role in both particle physics and cosmological phenomena. This project has a strong educational component which includes the training of graduate students for research as well as the mentoring of undergraduate physics majors. Likewise, the "TheoryNet" program will continue to cultivate interest and excitement for science among the young, to help prepare a future generation of potential scientists and educators.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.

该奖项为东北大学的Pran Nath，James Halverson，Brent D. Nelson和Tomasz R. Taylor的研究活动提供了资金。根据这项赠款，将在理论高能物理学的广泛主题进行研究。 These topics include many of the most exciting current research areas ranging from a unique kind of symmetry amongst the elementary particles called "supersymmetry" to speculative theories that might be able to unify quantum mechanics and gravity, such as string theory and F-theory, and studies of new ways of studying the behavior of particles when they scatter --- methods involving so-called "celestial amplitudes". 此外，机器学习工具将用于探索超出标准模型以外的基本物理的性质。预计将从大型强子对撞机（LHC）的RUN3以及各种天体物理实验中出现的新数据也将被探索，以获得除Electroweak和强相互作用的标准模型之外的新物理学的证据。这项研究将通过在美国当前知识的边界推进基本物理学来提高国家利益。这些研究项目还将涉及多个博士学位。在PI的指导下工作的学生。此外，该项目的一个重要部分是外展计划理论网络，它通过讲座和示范来促进波士顿地区理论家与高中生之间的直接互动。从技术上讲，要进行的研究旨在开发新的形式主义和工具，以研究超出能量量表的物理学性质。这包括与基于字符串和F理论的统一模型有关的理论工作，以及对天体振幅的进一步研究。这项工作还包括开发方法，以找到可能从LHC出现的新数据中的超对称性或字符串的证据。该项目还将包括将机器学习的应用用于探索弦乐景观和相关现象。该项目还将包括粒子理论和宇宙学的界面上的工作，包括一个更统一的框架，其中包括暗物质和暗能量。调查的另一个领域包括对隐藏部门的研究，这些扇区出现在广泛的超级弦模型和弦模型中，并且已经开始在粒子物理和宇宙学现象中起着越来越重要的作用。该项目具有强大的教育组成部分，其中包括培训研究生进行研究以及对本科生专业的指导。同样，“理论网”计划将继续在年轻人中培养对科学的兴趣和兴奋，以帮助准备未来的潜在科学家和教育工作者。该奖项反映了NSF的法定使命，并认为值得通过基金会的知识分子优点和更广泛的影响审查标准来通过评估来进行评估。
