Superconformal generalization of the chaotic inflation model

Year: 2013

Type: article

Abstract: A model of chaotic inflation based on the theory of a scalar field with potential λϕ 4 perfectly matches the observational data if one adds to it a tiny non-minimal coupling to gravity with ξ≳0.002. We describe embedding of this model into the superconformal theory with spontaneous breaking of superconformal symmetry, and into supergravity. A model with small ξ is technically natural: setting the small parameter ξ to zero leads to a point of enhanced symmetry in the underlying superconformal theory.
