Findings

Compatibility of models with Planck data analyzed

Impact of non-minimal gravity coupling assessed

Quadratic logarithmic potential studied in inflation context

Abstract

We apply the multiple point criticality principle to inflationary model building and study Coleman-Weinberg inflation when the scalar potential is quadratic in the logarithmic correction. We analyze also the impact of a non-minimal coupling to gravity under two possible gravity formulation: metric or Palatini. We compare the eventual compatibility of the results with the final data release of the Planck mission.
