Geometry of Kinematic Flow
Daniel Baumann, Harry Goodhew, Austin Joyce +3
We uncover a geometric organization of the differential equations for the wavefunction coefficients of conformally coupled scalars in power-law cosmologies. To do this, we introduc…

Bananas are Unparticles: Differential Equations and Cosmological Bootstrap
Tom Westerdijk, Chen Yang
We establish an exact correspondence between tree-level cosmological correlators with unparticle exchange (at integer scaling dimensions) and banana diagrams of conformally coupled…
