چکیده

It is usually supposed that inflation is of the slow-roll variety, and that the inflaton generates the primordial curvature perturbation. According to the curvaton hypothesis, inflation need not be slow-roll, and if it is the inflaton generates a negligible curvature perturbation. We find that the construction of slow-roll inflation models becomes much easier under this hypothesis. Also, thermal inflation followed by fast-roll becomes viable, with no slow-roll inflation at all.

Modular Inflation and the Curvaton

Supersymmetric Peccei-Quinn models which provide a suitable candidate for the curvaton field are studied. These models also solve the μ problem, while generating the Peccei-Quinn scale dynamically. The curvaton is a pseudo Nambu-Goldstone boson corresponding to an angular degree of freedom orthogonal to the axion. Its order parameter increases substantially following a phase transition during i...

paradigm can accommodate multiple low inflation scales

Recent arguments show that some curvaton field may generate the cosmological curvature perturbation. As the curvaton is independent of the inflaton field, there is a hope that the fine-tunings of inflation models can be cured by the curvaton scenario. More recently, however, D.H.Lyth discussed that there is a strong bound for the Hubble parameter during inflation even if one assumes the curvato...

Curvaton 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...

Curvaton scenario with low scale inflation revisited

In its simplest form the curvaton paradigm requires the Hubble parameter during inflation to be bigger than 10GeV, but this bound may be evaded in non-standard settings. In the heavy curvaton scenario the curvaton mass increases significantly after the end of inflation. We reanalyze the bound in this set up, taking into account the upper bound on the curvaton mass from direct decay. We obtain H...
