Research in theoretical physics of elementary particles and strings will include: Precision calculations of the quantum corrections to the Standard Model of elementary interactions. This kind of calculations has been crucial, already, to show that the Standard Model is the most successful theory of elementary interactions ever. In the present and future, it shall allow us to compare this theory with experiment, with accuracy sufficient to open a window on possible new physics. ii) Non-perturbative calculations in string theory. Strings are the only reliable theory of (perturbative) quantum gravity available today. Some calculations can be performed using to the fullest extent special symmetries (extended supersymmetry, duality etc.). These calculations are crucial in trying to understand the deepest aspect of string theory, as, for instance, to which degree it is unique. They also provide a powerful technique for understanding the physics of strongly interacting quantum fields.

基本粒子和弦的理论物理学研究将包括：对基本相互作用标准模型的量子修正的精确计算。这种计算已经证明了标准模型是有史以来最成功的基本相互作用理论。 在现在和将来，它将使我们能够将这个理论与实验进行比较，其精确度足以打开一扇通向可能的新物理学的窗户。 （2）弦理论中的非微扰计算。 弦是目前唯一可靠的（微扰）量子引力理论。 某些计算可以使用特殊对称性（扩展超对称性，对偶性等）来完成。 这些计算对于理解弦论的最深层次至关重要，例如，它在多大程度上是独一无二的。 它们还为理解强相互作用量子场的物理学提供了强有力的技术。
