Blue Perturbation Spectra from Hybrid Inflation with Canonical Supergravity
نویسنده
چکیده
We construct a hybrid inflationary model associated with the superheavy scale MX ∼ 1016 GeV of supersymmetric grand unified theories in which the inflaton potential is provided entirely by canonical supergravity. We find that the spectrum of adiabatic density perturbations is characterized by a strongly varying spectral index which is considerably larger than unity. Moreover, the total number of e-foldings is very limited. Implications of our analysis for other hybrid inflationary scenarios are briefly discussed.

Hybrid Inflation with Quasi-canonical Supergravity
We construct a hybrid inflationary model associated with the superheavy scale MX ≃ 2 × 1016 GeV of the minimal supersymmetric standard model which is based on the simplest superpotential for symmetry breaking and in which the inflaton potential along the inflationary trajectory is essentially provided by quasi-canonical supergravity. The resulting spectrum of adiabatic density pertubations is b...
متن کاملCosmic structure formation in Hybrid Inflation models
A wide class of inflationary models, known as Hybrid Inflation models, may produce topological defects during a phase transition at the end of the inflationary epoch. We point out that, if the energy scale of these defects is close to that of Grand Unification, then their effect on cosmic structure formation and the generation of microwave background anisotropies cannot be ignored. Therefore, i...
متن کاملBlue perturbation spectra from inflation.
We investigate inflationary models leading to density perturbations with a spectral index n > 1 (“blue spectra”). These perturbation spectra may be useful to simultaneously account for both the amount of ultra large-scale power required to fit cosmic microwave background anisotropies, such as those measured by COBE, and that required to give bulk motions and structures on the ∼ 50 h Mpc scale.
متن کاملCurvaton Potential Terms, Scale-Dependent Perturbation Spectra and Chaotic Initial Conditions
The curvaton scenario predicts an almost scale-invariant spectrum of perturbations in most inflation models. We consider the possibility that renormalisable φ4 or Planck scale-suppressed non-renormalisable curvaton potential terms may result in an observable deviation from scale-invariance. We show that if the curvaton initially has a large amplitude and if the total number of e-foldings of inf...
متن کاملF - term Hybrid Inflation in Effective Supergravity Theories
We show that the effective low energy supergravity theories which result from a generic string theory can provide a promising framework for models of hybrid inflation in which the potential energy which drives inflation originates from the F-term of the effective supergravity theory. In the class of models considered the inflaton is protected from receiving mass during inflation by a Heisenberg...
