Scalar QED in AdS

A Ankur, D Carmi, L Di Pietro - Journal of High Energy Physics, 2023 - arts.units.it
We consider scalar QED with Nf flavors in AdSD. For D< 4 the theory is strongly-coupled in
the IR. We use the spin 1 spectral representation to compute and efficiently resum the …

On holography in general background and the boundary effective action from AdS to dS

S Fichet - Journal of High Energy Physics, 2022 - Springer
A bstract We study quantum fields on an arbitrary, rigid background with boundary. We
derive the action for a scalar in the holographic basis that separates the boundary and bulk …

A Antunes, MS Costa, J Penedones… - Journal of High Energy …, 2021 - Springer
A bstract The boundary correlation functions for a Quantum Field Theory (QFT) in an Anti-de
Sitter (AdS) background can stay conformally covariant even if the bulk theory undergoes a …

Loops in de Sitter space

SL Cacciatori, H Epstein, U Moschella - arXiv preprint arXiv:2403.13145, 2024 - arxiv.org
We discuss general one and two-loops banana diagrams with arbitrary masses on the de
Sitter spacetime by using direct methods of dS quantum field theory in the dimensional …

Bootstrapping AdS2× S2 hypermultiplets: hidden four-dimensional conformal symmetry

Loops, recursions, and soft limits for fermionic correlators in (A) dS

C Chowdhury, P Chowdhury, RN Moga… - Journal of High Energy …, 2024 - Springer
A bstract 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 …
