New BCJ representations for one-loop amplitudes in gauge theories and gravity by Song He, Oliver Schlotterer, Yong Zhang

“…We explain a procedure to manifest the Bern–Carrasco–Johansson duality between color and kinematics in n-point one-loop amplitudes of a variety of supersymmetric gauge theories. Explicit amplitude representations are constructed through a systematic reorganization of the integrands in the Cachazo–He–Yuan formalism. …”

Perfecting one-loop BCJ numerators in SYM and supergravity by Alex Edison, Song He, Henrik Johansson, Oliver Schlotterer, Fei Teng, Yong Zhang

“…Abstract We take a major step towards computing D-dimensional one-loop amplitudes in general gauge theories, compatible with the principles of unitarity and the color-kinematics duality. …”
