Sub-eV Hubble scale inflation within gauge mediated supersymmetry breaking
Abstract
Minimal Supersymmetric Standard Model with gauge mediated supersymmetry breaking has all the necessary ingredients for a successful sub-eV Hubble scale inflation H inf 10-3-10-1 eV. The model generates the right amplitude for scalar density perturbations and a spectral tilt within the range, 0.90 ≤ ns ≤ 1. The reheat temperature is T R 10 TeV, which strongly prefers electroweak baryogenesis and creates the right abundance of gravitinos with a mass m3/2 100 keV to be the dark matter.
