WORKSHOP: Amplitudes 2010

散射振幅是规范理论和引力中的基本量。计算这些量的标准方法是路径积分在费曼图上的微扰展开，这涉及到复杂的计算。然而，结果往往出人意料地简单，这有力地表明，在这些理论中有未知的结构有待发现。这可能会彻底改变我们理解量子场论和弦理论的方式，并导致计算物理可观测性的新的和有效的方法。这次研讨会将致力于回顾在这一领域取得的进展，突出与扭曲和可积性的迷人联系，并促进参与者之间的互动和合作。

Scattering amplitudes are fundamental quantities in gauge theory and in gravity. The standard method for calculating these quantities is the perturbative expansion of the path integral in terms of Feynman diagrams, which involves complex calculations. However the results are often surprisingly simple, which suggests strongly that there is unknown structure to be discovered in these theories. This may revolutionise the way we understand quantum field theory and possibly string theory, and lead to novel and efficient methods for calculating physical observables.This Workshop will be devoted to reviewing progress made in this area, highlight the fascinating connections to twistors and integrability, and stimulate interaction and collaboration among the participants.
