Kinematic Hopf algebra and BCJ numerators at finite
Gang Chen, Laurentiu Rodina, Congkao Wen
In this letter, starting from a kinematic Hopf algebra, we first construct a closed-form formula for all Bern-Carrasco-Johansson (BCJ) numerators in Yang-Mills (YM) theory with inf…

Kinematic Hopf algebra for amplitudes from higher-derivative operators
Gang Chen, Laurentiu Rodina, Congkao Wen
Recently it has been shown that Bern-Carrasco-Johansson (BCJ) numerators of colour-kinematic duality for tree-level scattering amplitudes in Yang-Mills theory (coupled with scalars…
