Title: Off-shell Double Copy of Maximal Supersymmetry in D=4

Abstract:
The aim of this talk is to present an algebraic way to obtain N=8 supergravity as the off-shell double copy of N=4 super Yang-Mills theory up to the cubic order in fields. In particular, using the language of homotopy algebras we are able to rewrite the kinematic algebra and the global supersymmetry algebra in an abstract yet suitable way. This procedure allows us to prove that the double copy implies an enhancement of both the R-symmetry and the global supersymmetry. The talk is based on the recent paper 2501.02058.
