我们研究了用Sudakov变量表示的标量qcd中的树级五点振幅，并使用Bern， Carrasco和Johansson提出的颜色-运动学对偶找到等效的“引力”对应物。利用引力振幅的多雷格极限，我们证明了由两个雷格胶子与一个壳上胶子顶点的双重复制直接引起的两个雷格胶子与一个壳上胶子耦合中的那些片段是普适性的，并且可以被对偶性适当地再现。
A bstractWe investigate tree-level five-point amplitudes in scalar-QCD expressed in terms of Sudakov variables and find the equivalent “gravitational” counterparts using the color-kinematics duality proposed by Bern, Carrasco, and Johansson. Taking the multi-Regge limit in the gravitational amplitudes, we show that those pieces in the coupling of two reggeized gravitons to one on-shell graviton directly stemming from the double copy of the vertex for two reggeized gluons to one on-shell gluon are universal and properly reproduced by the duality.
