Abstract

We define a general class of superconformal inflationary attractor models [R. Kallosh et al., Phys. Rev. Lett. 112, 011303 (2014); J. High Energy Phys. 11 (2013) 198; A. Linde, arXiv:1402.0526, R. Kallosh, arXiv:1402.0527], which include, among others, inflationary models of “induced gravity” which were argued to retain perturbative unitarity up to the Planck scale [G. F. Giudice and H. M. Lee, arXiv:1402.2129]. The choice of the function f(ϕ) in superconformal attractors for the models introduced by Giudice and Lee [arXiv:1402.2129] is f(ϕ)=ϕnξ1. We present both superconformal and supergravity versions of these models, which were derived by Kallosh et al. [Phys. Rev. Lett. 112, 011303 (2014); J. High Energy Phys. 11 (2013) 198]; Linde [arXiv:1402.0526], Kallosh [arXiv:1402.0527] for arbitrary f(ϕ), together with the universal conditions required for stabilization of the extra three moduli present in the superconformal attractors, in addition to the inflaton.
