论文摘要
散射幅度的进步已经暴露了以前隐藏的颜色界和双层拷贝结构，从仪表和重力理论到有效的现场理论，例如手性扰动理论和出生的污染模型。这些新型结构既简化了高级计算，又提出了与统一框架相对论量子理论相关的诱人问题。这篇介绍性的迷你审查文章邀请了这些主题的进一步探索。在简要介绍了颜色二元性二元性和双副本之后，它们出现在树木和重力理论中的循环级别，我们提供了两个不同的例子：1）对双拷贝可构造理论的网络介绍，以及2）讨论有关与重力波物理学相关的双重副本的讨论。
Advances in scattering amplitudes have exposed previously-hidden color-kinematics and double-copy structures in theories ranging from gauge and gravity theories to effective field theories such as chiral perturbation theory and the Born-Infeld model. These novel structures both simplify higher-order calculations and pose tantalizing questions related to a unified framework underlying relativistic quantum theories. This introductory mini-review article invites further exploration of these topics. After a brief introduction to color-kinematics duality and the double copy as they emerges at tree and loop-level in gauge and gravity theories, we present two distinct examples: 1) an introduction to the web of double-copy-constructible theories, and 2) a discussion on the application of the double copy to calculation relevant to gravitational-wave physics.
