Superconformal generalization of the chaotic inflation model

A model of chaotic inflation based on the theory of a scalar field with potential ⁴ perfectly matches the observational data if one adds to it a tiny non-minimal coupling to gravity -/2 ² R with > 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 is technically natural: setting the small parameter to zero leads to a point of enhanced symmetry in the underlying superconformal theory.
