Interactions of Particles, Fields and Strings

拟议的研究涉及粒子、场和弦的小组研究。该小组建议探索超越标准模型的物理学，着眼于理解两个重要的微调问题，层次问题(为什么粒子的质量比普朗克质量大得多)和宇宙常量问题。在更高维度的背景下，层次问题变成了为什么额外的维度如此之大？PI打算探索离散化的额外维度，作为一种使用解构原理构建新的场论类别的方法。这是一种全新的建模方法。作为超对称性及其固有的粒子光谱加倍的替代方案，PI正在探索一种定性的新方法来解决分层问题，该方法基于拥有一个伪戈德斯通玻色子的光希格斯。这种方法被称为“小希格斯”模型，它对TeV物理有了新的预测。PI打算继续他们对对偶对称性的探索，以及使用弦几何进行量子场论的几何工程。

The proposed research involves group research in Particle, Fields and Strings. The group proposes to explore physics beyond the standard model with an eye on understanding two important fine-tuning problems, the hierarchy problem (why are the masses of the particles very different (much lighter) than the Planck mass) and the cosmological constant problem. In the context of higher dimensions, the hierarchy problem becomes why are the extra dimensions so large? The PI's intend to explore discretized extra dimensions as a method of constructing new classes of field theories using the principle of deconstruction. This is an entirely new method of model building. As an alternative to Supersymmetry and its inherent doubling of the spectrum of particles being the relevant physics expected at new colliders such as LHC, the PI's are exploring a qualitatively new approach to the hierarchy problem based on having a light Higgs that is a pseudo-Goldstone Boson. This approach is called the "little Higgs" model and it has new predictions for TeV Physics. The PI's intend to continue their exploration of duality symmetries as well as the geometric engineering of quantum field theories using string geometry.
