Query: Complete construction of magical, symmetric and homogeneous N=2
  supergravities as double copies of gauge theories   We show that scattering amplitudes in magical, symmetric or homogeneous N=2
Maxwell-Einstein supergravities can be obtained as double copies of two gauge
theories, using the framework of color/kinematics duality. The left-hand-copy
is N=2 super-Yang-Mills theory coupled to a hypermultiplet, whereas the
right-hand-copy is a non-supersymmetric theory that can be identified as the
dimensional reduction of a D-dimensional Yang-Mills theory coupled to P
fermions. For generic D and P, the double copy gives homogeneous
supergravities. For P=1 and D=7,8,10,14, it gives the magical supergravities.
We compute explicit amplitudes, discuss their soft limit and study the
UV-behavior at one loop.
