Cosmological models with non-minimally coupled scalar fields and renormalization-group inflationary scenarios

摘要

The possibility to construct an inflationary scenario for renormalization-group improved potentials corresponding to the Higgs sector of grant unification models is investigated. Taking into account quantum corrections to the renormalization-group potential which sums all leading logs of perturbation theory is essential for a successful realization of the inflationary scenario, with very reasonable parameters values. The inflationary models thus obtained are seen to be in good agreement with the most recent and accurate observational data.
