@article{Nohle2014ColorKinematicsDI, title={Color-Kinematics Duality in One-Loop Four-Gluon Amplitudes with Matter}, author={Josh Nohle}, journal={Physical Review D}, year={2014}, volume={90}, pages={025020} }

Four-point one-loop nonsupersymmetric pure Yang-Mills amplitudes with the duality between color and kinematics manifest have been constructed in previous work. Here, we extend the discussion to fermions and scalars circulating in the loop with all external gluons. This gives another nontrivial loop-level example showing that the duality between color and kinematics holds in nonsupersymmetric gauge theory. The construction is valid in any spacetime dimension and written in terms of formal…

Abstract
Many gauge theories possess a hidden duality between color and kinematics in their on-shell scattering amplitudes. An open problem is to formulate an off-shell realization of the duality,…
