Particle Theory in the LHC Era

过去十年的理论研究使人们对量子场论和弦理论有了新的认识。这些反过来又导致了超越标准模型的自然微观规律的新范式，并提高了我们分析这些理论的实验含义的能力。围绕电弱统一和暗物质本身性质的谜题，已经被理论家们与引人注目的新原理联系在一起，从超对称到额外时空维度，再到粒子合成。约翰·霍普金斯大学的理论小组由乔纳森·巴格、大卫·卡普兰和拉曼·桑德勒姆组成，他们提出在理论和实验的结合中解决核心问题，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造新的算法，开发和利用新的计算工具来区分新物理和标准模型过程，提出新的理论机制，并开发新的模型，最终有助于自然微观定律的综合。该项目具有重大的广泛影响。拟议的研究是研究生的一个很好的训练基地。此外，这一科学领域的兴奋值得广泛传播，霍普金斯理论小组在这一使命中发挥了重要作用。Bagger致力于阐明推动21世纪粒子物理学发展的新思想。他是量子宇宙团队的关键成员，该团队准备了突出粒子物理学和宇宙学之间联系的材料。他还与马里兰科学中心制作了一个关于大型强子对撞机（LHC）的天文馆节目。桑德勒姆是众多新闻媒体的顾问。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。卡普兰打算发展并呈现霍普金斯夸克网络项目的理论一面，旨在将高中教师与从事前沿研究的物理学家联系起来。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造和早期的纪录片。

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.
