David Pirtskhalava, Luca Santoni, Enrico Trincherini
Many alternatives to canonical slow-roll inflation have been proposed over the years, one of the main motivations being to have a model, capable of generating observable values of…

David Pirtskhalava, Luca Santoni, Enrico Trincherini +1
Canonical models of single-field, slow-roll inflation do not lead to appreciable non-Gaussianity, unless derivative interactions of the inflaton become uncontrollably large. We pro…
