All-loop group-theory constraints for four-point amplitudes of SU(N), SO(N), and Sp(N) gauge theories
Abstract In the decomposition of gauge-theory amplitudes into kinematic and color factors, the color factors (at a given loop order L) span a proper subspace of the extended trace space (which consists of single and multiple traces of generators of the gauge group, graded by powers of N). Using an i...
