Self-dual Yang-Mills and gravity from twistor actions

This paper constructs simple Lorentz-invariant twistor space actions for maximally supersymmetric self-dual Yang-Mills theory and self-dual gravity. The Yang-Mills action exhibits color-kinematics duality and double copies to the gravity action. The example illustrates a homotopy algebraic perspective on the double copy using a non-commutative Hopf algebra controlling momentum dependence.
