Color-factor symmetry using perturbiner methods for tree-level amplitudes of Yang-Mills theory coupled to matter
Abigail R. Chriss, Mia Karlsson, Stephen G. Naculich
Bern-Carrasco-Johansson relations are helicity-independent constraints among the partial amplitudes of tree-level processes containing gluons and possibly also matter fields. They…

All-loop group-theory constraints for four-point amplitudes of SU(), SO(), and Sp() gauge theories
Stephen G. Naculich, Athis Osathapan
In the decomposition of gauge-theory amplitudes into kinematic and color factors, the color factors (at a given loop order ) span a proper subspace of the extended trace space (…
