Résumé |
I will start with a broad overview of the theory of cosmological correlators.
After that, I will switch gears to the case of correlators of spinning particles.
I will show how the orthogonal Grassmannian turns out to be the natural kinematic
space for describing correlation functions of massless spinning particles, in four
dimensional (Anti)-de Sitter space.
In this kinematic space, tree-level cosmological correlators factorize in a simple
way and can be bootstrapped with rather ease, revealing some hidden beauty. |
