A model of chaotic inflation based on the theory of a scalar field with potential λφ{sup 4} perfectly matches the observational data if one adds to it a tiny non-minimal coupling to gravity -ξ/2φ{sup 2} R 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.
