Abstract: While much work has been devoted to understanding the structure of the perturbation theory of supergravity theories containing abelian vector fields, little is known about the scattering amplitudes of supergravities coupled to non-abelian vector fields. In this talk we explore an infinite class of gauged supergravity theories. We discuss the connection to their ungauged version, identify a double-copy structure, show how to compute their scattering amplitudes and discuss the potential for future studies of UV divergences in these theories.
