Description
Cosmological correlators encode rich information about quantum field theories in a cosmological background and are key observables of cosmological collider physics. However, their analytical computation is a hard problem due to the inherent complexities of these functions. Recently, we solved this problem for all tree-level massive correlators and revealed a universal structure of family trees. In this talk, I will introduce the recent progress on this front.
