A program of research in theoretical elementary particle physics willinclude the study of the relation between quantum field theory inthree-dimensional space on the one hand, and gravity and supergravity inhigher dimensions on the other hand. Quantum field theory describes suchphenomena as the strong nuclear forces. Supergravity is a limiting case ofthe string theory that may unify all of the forces of nature, includinggravity. It has been shown that the connection between quantum fieldtheory and gravity gives quantitative information about the properties offield theory when forces between particles are very strong. This strong -force information is required for many applications and is generally notaccessible by other methods.

理论基本粒子物理学的研究计划将包括一方面研究三维空间中的量子场论，另一方面研究高维空间中的引力和超引力之间的关系。量子场论把这种现象描述为强核力。超引力是弦理论的一个极限，它可以统一所有的自然力，包括引力。量子场论和引力之间的联系已经表明，当粒子间的力非常强时，量子场论和引力之间的联系给出了关于场论性质的定量信息。这种强力信息是许多应用所必需的，而且一般不能用其他方法获得.
