Higgs inflation, reheating and gravitino production in noscale Supersymmetric GUTs
Abstract
We extend our previous study of supersymmetric Higgs inflation in the context of noscale supergravity and grand unification, to include models based on the flipped SU(5) and the PatiSalam group. Like the previous SU(5) GUT model, these yield a class of inflation models whose inflation predictions interpolate between those of the quadratic chaotic inflation and Starobinskylike inflation, while avoiding tension with proton decay limits. We further analyse the reheating process in these models, and derive the number of efolds, which is independent of the reheating temperature. We derive the corresponding predictions for the scalar tilt and the tensortoscalar ratio in cosmic microwave background perturbations, as well as discussing the gravitino production following inflation.
