Description

A double copy between 2 > N QCD amplitudes and Gravity amplitudes was first discovered by Lipatov in 1981. In published work with G. Dvali, we showed how a double copy between Black Holes and the CGC arises, with both systems saturating the Bekenstein bound. We discuss common features in the collision and subsequent evolution of shockwaves in the two systems.In particular, we show how this dual picture points to some missing features of the CGC, and conversely how the CGC can help compute gravitational radiation in the vicinity of a Black Hole.
