Intermediate scale supersymmetric inflation, matter and dark energy
Intermediate scale supersymmetric inflation, matter and dark energy
We consider supersymmetric inflation models in which inflation occurs at an intermediate scale and which provide a solution to the µ problem and the strong CP problem. Such models are particularly attractive since inflation, baryogenesis and the relic abundance of cold dark matter are all related by a set of parameters which also affect particle physics collider phenomena, neutrino masses and the strong CP problem. For such models the natural situation is a universe containing matter composed of baryons, massive neutrinos, lightest superpartner cold dark matter and axions. The present-day relic abundances of these different forms of matter are (in principle) calculable from the supersymmetric inflation model together with a measurement of the cosmic microwave background temperature and the Hubble constant. From these relic abundances one can deduce the amount of the present-day dark energy density.

Abstract
We consider supersymmetric inflation models in which inflation occurs at an intermediate scale and which provide a solution to the µ problem and the strong CP problem. Such models are particularly attractive since inflation, baryogenesis and the relic abundance of cold dark matter are all related by a set of parameters which also affect particle physics collider phenomena, neutrino masses and the strong CP problem. For such models the natural situation is a universe containing matter composed of baryons, massive neutrinos, lightest superpartner cold dark matter and axions. The present-day relic abundances of these different forms of matter are (in principle) calculable from the supersymmetric inflation model together with a measurement of the cosmic microwave background temperature and the Hubble constant. From these relic abundances one can deduce the amount of the present-day dark energy density.
