Research in the broad area of theoretical elementary particle physics will concentrate on features within, and related to, superstring theory, the candidate fundamental theory of all forces at the atomic and subatomic level. An essential aspect of superstring theory is supersymmetry, a theoretical concept that puts pairs (or larger groupings) of superficially different particles into unified families, so-called supersymmetric multiplets. Much of the research will concentrate on studying properties of these supersymmetric systems in two-dimensions, where they form the basis of superstring constructions, and in our (space + time) four-dimensional world, where they are predicted by superstring theory to actually be experimentally observed. Ultimately, these studies will lead to new tools for investigating superstring theory and its implications, and eventually help unravel some of the mysteries that Nature has encoded in our physical world at the most fundamental level.

在理论基本粒子物理学的广泛领域的研究将集中在内部的功能，并与超弦理论，在原子和亚原子水平的所有力的候选基础理论。超弦理论的一个重要方面是超对称性，这是一个理论概念，将表面上不同的粒子对（或更大的群体）放入统一的家庭，即所谓的超对称多重态。 大部分研究将集中在研究这些超对称系统在二维和（空间+时间）四维世界中的性质，在二维世界中它们构成了超弦结构的基础，在我们的（空间+时间）四维世界中，它们被超弦理论预测为实际的。实验观察。 最终，这些研究将为研究超弦理论及其影响提供新的工具，并最终帮助解开自然界在最基本的层面上编码在我们物理世界中的一些奥秘。
