This award funds the research activities of Professors S. Dubovskiy, G. Gabadadze, M. Porrati, and A. Sirlin at New York University. The research activities of these four investigators center around several topics aimed at answering some of the truly fundamental questions in physics: How to best determine the fundamental constants of nature? What is the correct theory of gravity? What is gravity at cosmic scales? How is cosmology constrained by string theory or quantum gravity? Are there different models that explain the past and present accelerated expansion of the Universe? How can we describe strongly interacting subatomic matter? Can quantum gravity be solved in simple "toy model" settings? The PIs will work towards answering these questions both in parallel and in collaboration, involving postdocs and graduate students in the research process. As a result, 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, including the training of a new generation of scientists at all levels. Dissemination of results will also include review articles for specialized and popular science journals, organization of workshops, video- and Internet-based courses, and popular lectures. More technically, Professor Dubovskiy will continue to study many aspects of a special deformation of quantum field theories, called "T-T bar," and its applications to two-dimensional gravity, confining strings, and to a novel perspective on the hierarchy and cosmological-constant problems. Professor Gabadadze will search for possible UV-complete theories of massive gravity, and study holographic QCD as well as a theory of condensed-matter systems giving rise to equations for their sound modes that are identical to the ones Hawking solved to predict black-hole radiation. Professor Porrati will study simple models of gravity and supergravity, the infrared dynamics of gravity and ague theories, inflation in supergravity, and the link between massive gravity in three dimensions and conformal field theories. Professor Sirlin will apply a novel approach to evaluate electroweak corrections in important elementary particle-physics processes.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S教授的研究活动。杜博夫斯基湾Gabadadze，M. Porrati和A. Sirlin在纽约大学。这四位研究人员的研究活动围绕着几个主题，旨在回答物理学中一些真正的基本问题：如何最好地确定自然界的基本常数？什么是正确的引力理论？什么是宇宙尺度的引力？宇宙学如何受到弦理论或量子引力的约束？有没有不同的模型来解释宇宙过去和现在的加速膨胀？我们如何描述强相互作用的亚原子物质？量子引力能在简单的“玩具模型”中得到解决吗？PI将致力于回答这些问题，无论是在平行和合作，涉及博士后和研究生在研究过程中。因此，这一领域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，包括培训新一代各级科学家。成果的传播还将包括在专业和大众科学期刊上发表评论文章、组织讲习班、视频和互联网课程以及大众讲座。从技术上讲，Dubovskiy教授将继续研究量子场论的一种特殊变形的许多方面，称为“T-T棒”，以及它在二维引力、限制弦以及层次和宇宙常数问题上的新视角中的应用。Gabadadze教授将寻找可能的大质量引力的UV完整理论，并研究全息QCD以及凝聚态系统的理论，这些理论产生了与霍金解决预测黑洞辐射的声音模式相同的方程。 Porrati教授将研究引力和超引力的简单模型，引力和AGUE理论的红外动力学，超引力中的膨胀，以及三维大质量引力与共形场论之间的联系。 Sirlin教授将采用一种新的方法来评估重要的基本粒子物理过程中的电弱修正。该奖项反映了NSF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。
