More on Universal Superconformal Attractors (1402.3286v1)

Abstract: We define a general class of superconformal inflationary attractor models studied in our previous papers [1,2], which include, among others, inflationary models of 'induced gravity' which were argued to retain perturbative unitarity up to the Planck scale [3]. The choice of the function $f(\phi)$ in superconformal attractors for the models introduced in [3] is $f(\phi)= \phi^n - \xi^{-1}$. We present both superconformal and supergravity versions of these models, which were derived in [1,2] for arbitrary $f(\phi)$, together with the universal conditions required for stabilization of the extra three moduli present in the superconformal attractors, in addition to the inflaton.
