Soft limits of gluon amplitudes in holography and cosmology

Abstract: In this work, we extend the study of soft limits to (Anti) de Sitter spaces, investigating the analytic structure of holographic gluon correlators as part of a broader effort to reveal new symmetries and fundamental structures in gauge theories. By reorganizing perturbation theory in AdS to align with flat space unitarity, we analyze the contributions intrinsic to curved spacetime and their behavior in the soft limit. Our analysis uncovers schematic relations between $(n+1)$-point amplitude and $n$-point transition amplitudes in arbitrary-dimensional AdS, with explicit results derived for $n=4$ in AdS$_{d+1}$.
