Invoking increasingly higher dimension operators to encode novel UV physics in effective gauge and gravity theories traditionally means working with increasingly more finicky and difficult expressions. We find that the duality between color and kinematics provides a powerful tool towards drastic simplification. Local higher-derivative gauge and gravity operators at four points can be absorbed into simpler higher-derivative corrections to scalar theories, requiring only a small number of building blocks to generate gauge and gravity four-point amplitudes to all orders in mass dimension.
在有效的规范理论和引力理论中，引入越来越高维的算符来编码新的紫外物理，传统上意味着要处理越来越棘手和困难的表达式。我们发现，色与运动学之间的对偶性为大幅简化提供了一个强大工具。四点处的局域高阶导数规范算符和引力算符可以被吸收到对标量理论的更简单的高阶导数修正中，在质量维度上，只需少量的构建块就能生成规范和引力四点振幅的所有阶次。
