On Cosmological Correlators in Momentum Space

Kajal Singh

University of Liverpool

In this talk, I will discuss the progress in computing cosmological correlators in momentum space. Starting with a toy model of scalars, I will discuss some techniques borrowed from scattering amplitudes which simplify the computation of cosmological correlators in Yukawa, gauge, and gravity theories. Focusing on some basic diagrams, I will contrast the results for soft limits with the flat space results.
