The double copy of maximal supersymmetry in D = 4

Abstract We realize off-shell, local and gauge invariant N $$ \mathcal{N} $$ = 8 supergravity in D = 4, to cubic order in fields, as the double copy of N $$ \mathcal{N} $$ = 4 super Yang-Mills theory (SYM). Employing the homotopy algebra approach, we show that, thanks to a redundant formulation for...
