Summary:Title screen
We propose the unified models of cosmological inflation, spontaneous SUSY breaking, and the dark energy (de Sitter vacuum) in N=1N=1 supergravity with the dilaton-axion chiral superfield T in the presence of an N=1N=1 vector multiplet with the alternative Fayet-Iliopoulos term. By using the Kähler potential as K=−αlog(T+T¯¯¯¯)K=−αlog⁡(T+T¯) and the superpotential as a sum of a constant and a linear term, we find that viable inflation is possible for 3≤α≤αmax3≤α≤αmax where αmax≈7.235αmax≈7.235. Observations of the amplitude of primordial scalar perturbations fix the SUSY breaking scale in our models as high as 1013 GeV1013 GeV. In the case of α>3α>3 the axion gets the tree-level (non-tachyonic) mass comparable to the inflaton mass.
