Classical general relativity and gravitational waves from scattering amplitudes

该项目的目标是推动引力波研究的精度前沿，并开发新颖，高效的方法来提供急需的高精度模型，以与新的实验数据进行比较。该项目将广泛使用双重复制和BCJ双重性之间的颜色和运动学。我们将探讨自旋在黑洞散射中的作用，有效场论框架中由于高导数项而对广义相对论的偏离，以及与从环幅中提取广义相对论中的经典效应有关的概念问题。

The goal of this project will be to push the precision frontier in gravitational-wave research and develop novel, highly efficient methods to provide much needed high-precision models to compare with new experimental data. The project will make extensive use of the double copy and BCJ duality between colour and kinematics. We will explore the role of spin in black hole scattering, deviations from General Relativity due to higher-derivative terms in the framework of effective field theory, and conceptual issues related to the extraction of classical effects in General Relativity from loop amplitudes.
