QTC Journal Club: Bridging Celestial and (A)dS Holography

Speaker: Lorenzo Iacobacci, Postdoc at Brussel University
Abstract: 

We will explore the connection between Celestial and Euclidean Anti-de Sitter (EAdS) holography in the massive scalar case. Specifically, exploiting the so-called hyperbolic foliation of Minkowski space-time, we will show that each contribution to massive Celestial correlators can be reformulated as a linear combination of contributions to corresponding massive Witten correlators in EAdS. This result will be demonstrated explicitly for contact diagrams, and it extends to all orders in perturbation theory by leveraging the bootstrapping properties of CFTs.
