Double copy from momentum space to coordinate and Twistors space
In this talk I will introduce the double copy construction that allows us to write gravitational scattering amplitudes as the “square” of gauge theory ones. I will show how the standard construction can be generalized to include massive mediators and how this relationship can also be observed for classical solutions in coordinate space as well as for cohomology class representatives in twistor space. Throughout the talk I will focus on the example of Topologically Massive Theories.
