Asymptotic Symmetries of Massless QED in Even Dimensions
Daniel Kapec, Vyacheslav Lysov, Andrew Strominger
We consider the scattering of massless particles coupled to an abelian gauge field in 2n-dimensional Minkowski spacetime. Weinberg's soft photon theorem is recast as Ward identitie…

Semiclassical Virasoro Symmetry of the Quantum Gravity S-Matrix
Daniel Kapec, Vyacheslav Lysov, Sabrina Pasterski +1
It is shown that the tree-level S-matrix for quantum gravity in four-dimensional Minkowski space has a Virasoro symmetry which acts on the conformal sphere at null infinity.
