More on Universal Superconformal Attractors

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 $f(\varphi )$ in superconformal attractors for the models introduced in [3] is $f(\varphi )={\varphi }^n-{\xi }^{-1}$. We present both superconformal and supergravity versions of these models, which were derived in [1,2] for arbitrary $f(\varphi )$, together with the universal conditions required for stabilization of the extra three moduli present in the superconformal attractors, in addition to the inflaton.
