| Titre | Cosmological Scattering Equations |
| Résumé | In flat space, the scattering equations of Cachazo, He, and Yuan revolutionised the study of scattering amplitudes, revealing new double copy relations and new techniques for computing loop amplitudes and soft limits. In this talk, I will describe recent progress in extending this to cosmological observables, notably boundary correlators of certain scalar theories in four dimensional de Sitter space, which provide toy models for inflation. |
