Description
The Double Copy relations allow one to compute (super-)gravitational scattering amplitudes from (super-)Yang-Mills ones. We explore this paradigm off-shell by attempting the construction of $\mathcal{N}=1$ and $\mathcal{N}=2$ Supergravity Lagrangians using suitably chosen pairs of (super-)Yang-Mills theories as building blocks. Our double-copy fields and gauge symmetries are defined as convolution products of single-copy Yang-Mills fields and parameters. When extended to higher spins, the model allows for an interpretation of the latter in terms of either double or multiple copies.
