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.

散射振幅是规范理论和引力理论中的基本量。计算这些量的标准方法是费曼图中路径积分的微扰展开，这涉及复杂的计算。然而，结果往往是令人惊讶的简单，这强烈表明，有未知的结构被发现在这些理论。这可能会彻底改变我们理解量子场论和弦论的方式，并导致计算物理观测量的新的和有效的方法。本次研讨会将致力于回顾在这一领域取得的进展，突出扭曲和可积性的迷人联系，并激发参与者之间的互动和合作。
