Soft Photon, Gluon and Graviton Theorems in (A)dS from Conformal Invariance
arXiv:2506.11766
Abstract
We present new soft theorems for photon, gluon, and graviton correlators at tree level in (Anti)-de Sitter space. The results are derived by applying conformal Ward identities to constrain the structure of Witten diagrams.
