Off-shell color-kinematics duality for Chern-Simons
Off-shell color-kinematics duality for Chern-Simons
A bstract 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, thus manifesting a kinematic algebra. We show that 3D Chern-Simons (CS) theory in Lorenz gauge obeys off-shell color-kinematics duality. This …
