Abstract:

"Supergravity scattering amplitudes in general space-time dimension have the remarkable property that they can be constructed out of double copies of Yang-Mills interactions. In three dimensions, they can also be built out of double copies of Chern-Simons-matter interactions. This holds when these gauge theories exhibit a duality between color and kinematics. For Yang-Mills this property implies the existence of a kinematic Lie 2-algebra, and for Chern-Simons-matter this implies a kinematic Lie 3-algebra."
