Description
Summary:A bstract Recently a broad class of superconformal inflationary models was found leading to a universal observational prediction and [1, 2]. Here we generalize this class of models by introducing a parameter α inversely proportional to the curvature of the inflaton Kähler manifold. In the small curvature (large α ) limit, the observational predictions of this class of models coincide with the predictions of generic chaotic inflation models. However, for sufficiently large curvature (small α ), the predictions converge to the universal attractor regime with and , which corresponds to the part of the n s − r plane favored by the Planck data.
