| « Bootstrapping cosmological correlators » |

David Stefanyszyn |
| I will introduce the new cosmological bootstrap program and motivate it as a new tool to compute cosmological observables. I will explain how recent progress has vastly improved our understanding of quantum field theory in de Sitter space and on inflationary backgrounds, and how we can use bootstrap techniques to efficiently construct inflationary bispectra. I will also outline upcoming work where we use bootstrap tools to derive the four-point function of massless gravitons in de Sitter space. |
