Description
This talk reports on recent progress in amplitude computations for broad
classes of N=2 Maxwell-Einstein and Yang-Mills-Einstein supergravities,
using the framework provided by color/kinematics duality and the
double-copy construction.
After a review of the main theoretical tools, we discuss the extension
of the double-copy construction to a particular infinite family of N=2
Maxwell-Einstein theories in four and five dimensions, the generic
Jordan family of supergravities.
We show that the global symmetries of these theories can be easily
gauged, giving the amplitudes of the corresponding Yang-Mills-Einstein
supergravities. We also discuss how the construction can be modified to
describe spontaneous symmetry breaking. Finally, we present an extension
of the construction that captures an even larger class of N=2
supergravities with homogeneous target spaces.
