Relaxing Constraints on Inflation Models with Curvaton

High Energy Physics - Phenomenology 2009-11-11 v1 Astrophysics

Abstract

We consider the effects of the curvaton, late-decaying scalar condensation, to observational constraints on inflation models. From current observations of cosmic density fluctuations, severe constraints on some class of inflation models are obtained, in particular, on the chaotic inflation with higher-power monomials, the natural inflation, and the new inflation. We study how the curvaton scenario changes (and relaxes) the constraints on these models.
