Soft Photon, Gluon and Graviton Theorems in (A)dS from Conformal Invariance (2506.11766v1)
Published 13 Jun 2025 in hep-th and gr-qc
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.
