Kinematic Flow for Cosmological Loop Integrands
Daniel Baumann, Harry Goodhew, Hayden Lee
Recently, an interesting pattern was found in the differential equations satisfied by the Feynman integrals describing tree-level correlators of conformally coupled scalars in a po…

Tensor Integrals in the Large-Scale Structure
Hayden Lee
We present a new method for evaluating tensor integrals in the large-scale structure. Decomposing a CDM-like universe into a finite sum of scaling universes using the FFTLog, we…
