Title: Cosmology and Unification

Abstract: Precision measurements of primordial correlators in the CMB, Large Scale Structure, and 21-cm cosmology may contain “on-shell” imprints of extremely heavy particle physics, with masses at or even above the inflationary Hubble scale, via the remarkable inflationary mechanism(s) known as “cosmological collider physics”. I will describe new robust mechanisms for extending the energy-range and strength of such signals, and applications to far-UV scenarios such as grand unification, extra dimensions, the fate of the hierarchy problem, and inflation itself.
