Research in Particle Theory

理论基本粒子物理学的研究将侧重于基本相互作用的物理学，这些相互作用超出了目前所理解的能量范围。 对这些新相互作用的研究将使用基于超对称性和超弦理论的统一理论结构。 超对称性和超弦提供了一个框架，可以导致所有力的完全统一，包括引力。 该项目将开展的研究将侧重于超级对撞机实验和暗物质搜索中的统一特征。 调查的其他方面将集中在模型构建的更多理论方面。 还将进行研究，看看在下一代加速器可以达到的能量领域中是否可以实现力的统一。这些研究具有重要意义，因为在不久的将来，在超级对撞机上可以实现的能量下的物理学性质可以解开出现在一类具有低统一尺度的弦理论中的新的时空维度。 即将进行的研究将确定这些额外维度在精密测量中的影响，这些测量将在费米实验室的Tevatron和瑞士日内瓦欧洲核子研究中心的大型强子对撞机上进行。

Research in theoretical elementary particle physics will focus on the physics of fundamental interactions that lie beyond the currently understood regime of energies. Investigations of these new interactions will use the theoretical structures of unification based on supersymmetry and superstring theories. Supersymmetry and superstrings provide a framework which could lead to the full unification of all forces, including gravity. The research to be carried out in this project will focus on signatures of unification in supercollider experiments and in dark matter searches. Other aspects of the investigations will focus on more theoretical aspects of model building. Studies will also be conducted to see if the unification of forces can occur in the realm of energies that can be reached in the next generation of accelerators. These investigations are of significance since the nature of physics at energies that will be achievable in the near future at supercolliders can unravel new dimensions of space time that appear in a class of string theories with a low unification scale. Research to be carried out will identify the effects of these extra dimensions in precision measurements that will be made at the Tevatron at Fermilab and at the Large Hadron Collider at CERN, Geneva, Switzerland.
