A number of theoretical investigations in theoretical elementary particle physics will be carried out, focusing primarily on the physics of the strongly interacting particles as described by the quantum chromodynamic theory which is widely accepted as the correct fundamental description of the nuclear force. The methods used will involve extensive computations on massively parallel dedicated computers. An important specific aim of the research is an accurate (few percent) calculation from the fundamental theory of the electromagnetic fine structure of the spectrum of strongly interacting particles. This will be one of the first precise tests of quantum chromodynamics, which up to now has only been tested at best at the 5-10% level. In addition, this research program is the first to allow an accurate determination of the masses of the quarks, the fundamental building blocks of all known strongly interacting particles.

在理论基本粒子物理学的一些理论研究将进行，主要集中在强相互作用粒子的物理学所描述的量子色动力学理论被广泛接受为正确的基本描述核力。 所使用的方法将涉及大规模并行专用计算机上的大量计算。 该研究的一个重要具体目标是从强相互作用粒子光谱的电磁精细结构的基本理论中精确（百分之几）计算。 这将是量子色动力学的第一个精确测试之一，到目前为止，量子色动力学最多只能在5-10%的水平上进行测试。 此外，这项研究计划是第一个允许精确确定夸克质量的研究计划，夸克是所有已知强相互作用粒子的基本组成部分。
