Color-kinematics duality and the Regge limit of inelastic amplitudes

A bstract We 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 amplitu...

Summary:A bstract We 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.
