abstract
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 old relation, for the case of massless QED, as an infinitesimal symmetry of the S-matrix. The symmetry is shown to be locally generated by a vector field on the conformal sphere at null infinity. Explicit expressions are constructed for the associated charges as integrals over null infinity and shown to generate the symmetry. These charges are local generalizations of electric and magnetic dipole charges.

Symmetry uniquely fixes finite-time Faddeev-Kulish dressings in QED and gravity so they reproduce classical memory, allowing recovery of first-order and higher-order gravitational memory in perturbative calculations.
Subleading Chern-Simons soft factors stay insensitive to perturbative 1/ℓ² de Sitter corrections, indicating topological universality at the amplitude level.
