Prospects for cosmological collider physics
Speaker(s): Moritz Munchmeyer
Abstract: If heavy fields are present during inflation, they can leave an imprint in late-time cosmological observables. The main signature of these fields is a small amount of distinctly shaped non-Gaussianity, which if detected, would provide a wealth of information about the particle spectrum of the inflat... read more

PIRSA:15100067  ( MP4 Medium Res , MP3 , PDF ) Which Format?
Oscillations in the CMB bispectrum - Theory and data analysis
Speaker(s): Moritz Munchmeyer
Abstract: Oscillating signatures in the correlation functions of the primordial density perturbations are predicted by a variety of inflationary models. A theoretical mechanism that has attracted much attention is a periodic shift symmetry as implemented in axion monodromy inflation. This symmetry leads to re... read more
