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…
Low's Subleading Soft Theorem as a Symmetry of QED
Vyacheslav Lysov, Sabrina Pasterski, Andrew Strominger
It was shown by F. Low in the 1950s that the subleading terms of soft photon S-matrix elements obey a universal linear relation. In this paper we give a new interpretation to this…
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.
BMS supertranslations and Weinberg's soft graviton theorem
Temple He, Vyacheslav Lysov, Prahar Mitra +1
Recently it was conjectured that a certain infinite-dimensional "diagonal" subgroup of BMS supertranslations acting on past and future null infinity ( and ${\mathsc…
