We clarify inflaton models by considering them as effective field theories in the Ginzburg-Landau spirit. In this new approach, the precise form of the inflationary potential is constructed from the present WMAP data, and a useful scheme is prepared to confront with the forthcoming data. In this approach, the WMAP statement excluding the pure {phi}{sup 4} potential implies the presence of an inflaton mass term at the scale m{approx}10{sup 13} GeV. Chaotic, new and hybrid inflation models are… Expand
