If you have a question about this talk, please contact Ian A. Morrison. An inflationary regime for which more than 60 e-folds are generated classically during the waterfall phase occuring after the usual hybrid inflation has been identified. By performing a bayesian Monte-Carlo-Markov-Chain analysis, this scenario is shown to take place in a large part of the parameter space of the model. When this occurs, the observable perturbation modes leave the Hubble radius during waterfall inflation. The power spectrum of adiabatic perturbations is red, possibly in agreement with CMB constraints. A particular attention has been given to study only the regions for which quantum backreactions do not affect the classical dynamics. Implications concerning the preheating and the absence of topological defects in our universe will be discussed. This talk is part of the DAMTP Friday GR Seminar series.
