In the first work we pointed out that in such a model curvature perturbations are generated after the end of the slow-roll phase of inflation. In this work we develop further the observational implications of the model and compute the degree of non-Gaussianity predicted in the scenario. We find that the corresponding nonlinearity parameter, $f_{NL}$, can be as large as 10^2.7 pages, 1 figureAstrophysicsHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
