Title: Cosmology with a master coupling in flipped SU(5)×U(1): The λ6 universe

Abstract

We propose a complete cosmological scenario based on a flipped SU(5) × U(1) GUT model that incorporates Starobinsky-like inflation, taking the subsequent cosmological evolution carefully into account. A single master coupling, λ6, connects the singlet, GUT Higgs and matter fields, controlling 1) inflaton decays and reheating, 2) the gravitino production rate and therefore the non-thermal abundance of the supersymmetric cold dark matter particle, 3) neutrino masses and 4) the baryon asymmetry of the Universe.
