The past decade of theoretical research has given rise to new insights in quantum field theory and string theory. These in turn have led to new paradigms for the microscopic laws of nature beyond the Standard Model, and to advances in our ability to analyze the experimental implications of such theories. Puzzles surrounding electroweak unification and the nature of dark matter itself have been tied by theorists to dramatic new principles, ranging from supersymmetry to extra spacetime dimensions to particle compositeness. The Johns Hopkins theory group, consisting of Jonathan Bagger, David E. Kaplan, and Raman Sundrum, proposes to tackle central problems at the juncture of theory and experiment, while advancing understanding of core theoretical principles and mechanisms. This work will create new algorithms for experimental searches, develop and exploit new calculational tools needed to discriminate new physics from Standard Model processes, propose new theoretical mechanisms, and develop new models that may ultimately help in the grand synthesis of nature's microscopic laws. This project has significant broader impacts. The proposed research is an excellent training ground for graduate students. Moreover, the excitement of this field of science deserves to be disseminated broadly, and the Hopkins theory group plays a significant role in this mission. Bagger is deeply involved in articulating the new ideas that drive the particle physics of the twenty-first century. He was a key member of the Quantum Universe team that prepared materials highlighting the connections between particle physics and cosmology. He also produced a planetarium show about the Large Hadron Collider (LHC) with the Maryland Science Center. Sundrum acts as a consultant to a wide range of news media. He is writing a popular book on the physics of, and experimental search for, extra dimensions. Kaplan intends to develop and present a theoretical side to the Hopkins Quark Net program, aimed at connecting high school teachers with physicists engaged in cutting-edge research. He is also filming a documentary concerning the construction and early days of the Large Hadron Collider at CERN.

过去十年的理论研究在量子场论和弦理论中产生了新的见解。这些反过来又导致了超越标准模型的微观自然定律的新范式，并提高了我们分析这些理论的实验含义的能力。围绕着电弱统一和暗物质本身的性质的谜题已经被理论家们与戏剧性的新原理联系在一起，从超对称到额外的时空维度到粒子的复合性。约翰霍普金斯的理论小组，包括乔纳森·巴格，大卫E.卡普兰和拉曼Sundrum，建议解决在理论和实验的交界处的中心问题，同时推进对核心理论原理和机制的理解。这项工作将为实验搜索创建新的算法，开发和利用区分新物理与标准模型过程所需的新计算工具，提出新的理论机制，并开发可能最终有助于大自然微观定律综合的新模型。该项目具有广泛的影响。 拟议的研究是一个很好的研究生培训基地。 此外，这一科学领域的令人兴奋之处值得广泛传播，而霍普金斯理论小组在这一使命中发挥着重要作用。巴格深入参与阐明了推动21世纪粒子物理学的新思想。他是量子宇宙团队的关键成员，该团队准备了强调粒子物理学和宇宙学之间联系的材料。他还与马里兰州科学中心一起制作了一个关于大型强子对撞机（LHC）的天文馆节目。Sundrum担任各种新闻媒体的顾问。他正在写一本关于额外维度的物理学和实验研究的畅销书。卡普兰打算发展和提出一个理论方面的霍普金斯夸克网络计划，旨在连接高中教师与从事尖端研究的物理学家。 他还在拍摄一部关于欧洲核子研究中心大型强子对撞机的建设和早期的纪录片。
