Particle and Quantum Field Theory Investigations

基本粒子和弦的理论物理研究将包括：基本相互作用标准模型的量子修正的精确计算。这种计算已经起到了至关重要的作用，它证明了标准模型是迄今为止最成功的基本相互作用理论。在现在和将来，它将使我们能够把这个理论与实验进行比较，其精确度足以为可能的新物理学打开一扇窗。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。一些计算可以使用到最大程度的特殊对称性（扩展超对称，对偶性等）来执行。这些计算对于试图理解弦理论最深层的方面是至关重要的，例如，弦理论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一种强大的技术。

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.
