Abstract

Curvaton reheating is studied in non-oscillatory models of inflation, with the aim of obtaining bounds on the parameters of curvaton models and finding out whether low scale inflation can be attained. Using a minimal curvaton model, it is found that the allowed parameter space is considerably larger than in the case of the usual oscillatory inflation models. In particular, inflation with a Hubble scale as low as 1 TeV is comfortably allowed.
