Curvature perturbation from symmetry breaking the end of inflation

Year: 2006

Type: article

Abstract: We consider a two-field hybrid inflation model, in which the curvature perturbation is predominantly generated at the end of inflation. By finely tuning the coupling of the fields to the waterfall we find that we can get a measurable amount of non-Gaussianity.
