The objective if this research program is to generate new knowledge on the frontiers of theoretical elementary particle physics with the aim of achieving a better understanding of nature at its most fundamental level. This includes the incubation and development of new ideas in string theory and quantum field theory and on applying them to the understanding of the physics of elementary particles at the high energy frontier. One focus is the application of AdS/CFT duality to learn as much as possible about the behavior of gauge field theories in their strong coupling regime. In the current ``age of the LHC'', it is expected that the Higgs particle and perhaps other particles which would give hints about physics beyond the standard model could be discovered within the next few years. There is the distinct possibility that the electroweak sector of the standard model is more strongly coupled than was anticipated and our strategy is to derive new techniques and results about strongly coupled gauge theories with the aim of being able to study strong coupling physics at the TeV scale when hints as to what this physics might be emerge. This will include a fresh look at ideas such as the technicolor mechanism for dynamical symmetry breaking.

这一研究计划的目的是在理论基本粒子物理学的前沿产生新的知识，目的是在最基本的层面上更好地理解自然。这包括孕育和发展弦理论和量子场论的新思想，并将它们应用于理解高能前沿的基本粒子物理。其中一个焦点是应用ADS/CFT对偶来尽可能多地了解规范场理论在其强耦合区域的行为。在目前的“大型强子对撞机时代”，希格斯粒子和其他可能给出超越标准模型的物理线索的粒子有望在未来几年内被发现。有一种明显的可能性是，标准模型的电弱部分比预期的更强耦合，我们的策略是导出关于强耦合规范理论的新技术和结果，目的是能够在TeV尺度上研究强耦合物理，当有迹象表明这种物理可能是什么时。这将包括对动态对称性破缺的彩色机制等想法的全新审视。
