Title:Temporal enhancement of super-horizon curvature perturbations from decays of two curvatons and its cosmological consequences

Abstract:If more than one curvaton dominate the Universe at different epochs from each other, curvature perturbations can be temporarily enhanced to a value much larger than the observed one 10^{-5}. The traces of the enhancement may be left as higher order correlation functions.
