Flattening the inflaton’s potential with quantum corrections. II

In a previous paper I showed that a classical scalar potential with V^''/V~1 can be sufficiently flattened by quantum corrections to give rise to slow-roll inflation. In this paper I give a hybrid inflation implementation of that idea which can naturally produce a spectral index in the observationally viable range even for V1/4~10¹⁰--10¹¹ GeV. Although any observationally viable spectral index can be obtained, the model does predict a distinctive spectral shape.
