Abstract
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 of large gauge symmetries We analyze these Green’s functions in consid erable detail and show that they form a hierarchy of functions which describe ‘boundary to bulk’ propagators for large U1 gauge parameters supertranslations and sphere vector fields respectively As a consistency check we verify that the Green’s functions associated to the large diffeomorphisms map the Poincare group at null infinity to the Poincare group at timelike infinityThis article is published under an open access license Please check the Copyright Information section for details of this license and what reuse is permitted If your intended use exceeds what is permitted by the license or if you are unable to locate the licence and reuse information please contact the Rights and Permissions team
