Research in theoretical elementary particle physics will include studies of Quantum Chromo-Dynamics (QCD), which is the strong force that binds the constituent gluons and quarks to form a proton or neutron. New techniques will be used to investigate the production of massive quarks at particle colliders over a range of energy scales and also to investigate the QCD scattering of particles at very high energies. Since the theory of QCD is very complex in general, the study of its effects in specific relevant processes is important to gain insight into this theory. In addition, the understanding of QCD background interactions is crucial to the interpretation of high energy collider data which are being used to search for evidence of new physics.

理论基本粒子物理学的研究将包括量子色动学（QCD）的研究，这是一种结合组成胶子和夸克形成质子或中子的强力。 新的技术将被用来调查生产的质量夸克在粒子对撞机在一系列的能量尺度，也调查QCD散射的粒子在非常高的能量。 由于QCD理论总体上是非常复杂的，因此研究它在特定相关过程中的效应对于深入理解这一理论是非常重要的。 此外，对QCD背景相互作用的理解对于解释高能对撞机数据至关重要，这些数据正被用来寻找新物理的证据。
