Gravity=(gauge)^2 for soft gravitons

Abstract: Recently it has been realized that subleading corrections to soft theorems in gauge theories and gravity are related to the asymptotic symmetries of the theory at null infinity. In this talk I will discuss how in the case of the soft graviton theorem these corrections, when written in terms of kinematic invariants, exhibit a double copy structure for the emitted graviton. This result holds also in the Gribov limit, where emitted gravitons are not necessarily soft.
