This award funds the research activities of Professors Pran Nath, Brent D. Nelson, and Tomasz R. Taylor at Northeastern University.Thus far, data from the Large Hadron Collider (LHC) has been highly successful and has led to the discovery of the Higgs boso, which was the last missing piece of the Standard Model of particle physics. However, future data expected from the LHC will explore the nature of physics beyond the Standard Model. As part of their research, Professors Nath, Nelson, and Taylor will conduct studies aimed at finding clues of such new physics in upcoming data from the LHC and well as in astrophysical data. In their work, Professors Nath, Nelson, and Taylor will use models based on a symmetry known as "supersymmetry" which relates particles of different spins to each other, and on string theory, an approach to physics at very high energies which purports to unify all forces of nature, including gravity. This area of research serves the national interest as it advances our knowledge of the fundamental laws of nature at the frontiers of current knowledge. In addition, there is a strong educational component to this research. Several Ph.D. thesis students will be involved in these research projects. Likewise, Professors Nath, Nelson, and Taylor will disseminate their research through publications, conference and workshop presentations, and popular lectures. In addition, an important element of the proposal is "TheoryNet". This is an outreach program consisting of direct interactions between Boston-Area theorists and high-school students, through lecture presentations and demonstrations.More technically, Professors Nath, Nelson, and Taylor will conduct studies of dark matter in unified models based on supergravity and strings which contain possible dark-matter candidates, including those in a hidden sector. They will also conduct further theoretical work related to unified models based on strings and F-theory and they will conduct further investigations into the structure of string amplitudes. They will also investigate areas where particle theory overlaps with cosmology, specifically in the study of inflation and dark energy, and search for a unified framework for both. Finally, they will develop strategies to search for new physics in precision analyses which have the potential to probe physics at scales far beyond the reach of current or future accelerators.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，Brent D. Nelson教授，Brent D. Nelson和Tomasz R. Taylor的研究活动提供了资金。此外，来自大型强子撞机（LHC）的数据取得了很大的成功，并导致了Higgs Boso的发现，这是Higgs Boso，这是最后一次缺少标准粒子物理学标准的缺失模型。 但是，LHC预期的未来数据将探索超出标准模型的物理性质。 作为研究的一部分，Nath，Nelson和Taylor教授将进行旨在从LHC以及天体物理数据中以及即将到来的数据中找到此类物理学线索的研究。 在他们的工作中，Nath，Nelson和Taylor教授将使用基于称为“超对称性”的对称性的模型，该模型将不同自旋的颗粒彼此相关联，并且基于弦理论，是一种非常高能量的物理学方法，这些方法旨在统一所有自然力量，包括重力，包括重力。 该领域的研究领域为国家利益提供了促进我们对当前知识前沿的自然基本定律的了解。 此外，这项研究还有很强的教育组成部分。 几位博士论文学生将参与这些研究项目。 同样，纳斯（Nath）教授，纳尔逊（Nelson）和泰勒（Taylor）将通过出版物，会议和讲习班演讲以及大众讲座传播他们的研究。 另外，该提案的重要要素是“理论网”。 这是一个外展计划，包括通过演讲和演示，包括波士顿地区理论家与高中生之间的直接互动。从技术上讲，更多的是，Nath，Nath，Nelson和Taylor教授将在基于超级实力和弦乐的统一模型中对统一模型进行研究，这些模型包含可能的黑暗候选人，其中包括隐藏的部门，包括隐藏的部门。 他们还将基于字符串和F理论进行与统一模型有关的进一步理论工作，并将对弦振幅的结构进行进一步的研究。 他们还将研究粒子理论与宇宙学重叠的领域，特别是在通货膨胀和暗能量的研究中，并为两者寻找统一的框架。 最后，他们将制定策略在精确分析中寻找新物理学的策略，这些分析有可能以远远超出当前或将来的加速器的范围来探测物理学。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准来通过评估来获得支持的。
