Description
A double copy between 2 > N QCD amplitudes and Gravity amplitudes at high energies was first discovered by Lipatov in 1981. In published work with G. Dvali[1], we showed how a double copy between Black Holes and the CGC arises, with both systems saturating the Bekenstein bound. We discuss how this dual picture points to some missing features of the CGC. Most importantly theoretical techniques developed for the CGC allows one to compute gravitational radiation [2] in so-called close hyperbolic encounters of primordial blackholes accessible at next-generation gravitational wave observatories.
