Titre |
Bootstrapping Inflationary Correlators in Mellin Space |
|
Résumé |
The bootstrap philosophy has found remarkable successes in the context of
Conformal Field Theories. These advances were mostly consequences of powerful non-
perturbative implementations of causality and unitarity which translated into key
results in the context of the dual gravitational theories in Anti de Sitter space.
In this talk I will discuss recent progress towards the analogous problem in de
Sitter space. Making use of a recently introduced Mellin-Barnes representation for
momentum space correlators, I will discuss how to express dS exchange amplitudes
in terms of AdS ones and how to employ conformal bootstrap methods like the
spectral representation, Mellin Amplitudes and crossing decomposition in de Sitter
space. |
