# Curvaton with Polynomial Potential - High Energy Physics - Theory

Abstract: In general a weakly self-interacting curvaton field is expected and thecurvaton potential takes the polynomial form. The curvaton potential can bedominated by the self-interaction term during the period of inflation if thecurvaton field stays at a large vacuum expectation value. We use the $\delta{\cal N}$ formalism to calculate the primordial curvature perturbation in thevarious possible scenarios which make the curvaton model much richer.
