Null to time-like infinity Green's functions for asymptotic symmetries in Minkowski spacetime
Miguel Campiglia
We elaborate on the Green's functions that appeared in [1,2] when generalizing, from massless to massive particles, various equivalences between soft theorems and Ward identities o…
Asymptotic symmetries of gravity and soft theorems for massive particles
Miguel Campiglia, Alok Laddha
The existing equivalence between (generalized) BMS Ward identities with leading and subleading soft graviton theorems is extended to the case where the scattering particles are mas…
Asymptotic symmetries of QED and Weinberg's soft photon theorem
Miguel Campiglia, Alok Laddha
Various equivalences between so-called soft theorems which constrain scattering amplitudes and Ward identities related to asymptotic symmetries have recently been established in ga…
New symmetries for the Gravitational S-matrix
Miguel Campiglia, Alok Laddha
In [15] we proposed a generalization of the BMS group G which is a semidirect product of supertranslations and smooth diffeomorphisms of the conformal sphere. Although an extension…
