Amplitudes, Hopf algebras and the colour-kinematics duality
Andreas Brandhuber, Graham R. Brown, Gang Chen +3
It was recently proposed that the kinematic algebra featuring in the colour-kinematics duality for scattering amplitudes in heavy-mass effective field theory (HEFT) and Yang-Mills…

Kinematic Hopf algebra for amplitudes and form factors
Gang Chen, Guanda Lin, Congkao Wen
We propose a kinematic algebra for the Bern-Carrasco-Johansson (BCJ) numerators of tree-level amplitudes and form factors in Yang-Mills theory coupled with bi-adjoint scalars. The…
