A remarkably simple covariant graviton propagator in Anti-de Sitter spacetime
Radu N. Moga, Kostas Skenderis
We present remarkably simple covariant expressions for the graviton and ghost propagators in Anti-de Sitter (AdS) spacetime valid in any spacetime dimension. In gravity there is a…

Bulk-to-bulk photon propagator in AdS
Radu N. Moga, Kostas Skenderis
We study the photon bulk-to-bulk propagator in AdS in various gauges, including axial, Coulomb, and the standard covariant gauge. We compute the propagator using both momentum and…

Loops, Recursions, and Soft Limits for Fermionic Correlators in (A)dS
Chandramouli Chowdhury, Pratyusha Chowdhury, Radu N. Moga +1
Study of correlation functions in AdS/CFT and in-in correlators in de Sitter space often requires the computation of Witten diagrams. Due to the complexity of evaluating radial int…
