Large Field Inflation in Supergravity
نویسنده
چکیده
We present a supergravity inflationary scenario in which the inflaton field takes values considerably larger than the Planck scale. It is based on a class of inflationary potentials which can be derived from “singular” Kähler potentials assuming simple superpotentials of the type W ∼ S. To this class belong, among many others, all potentials which are even infinitesimally smaller than the one derived from the minimal Kähler potential. Our scenario allows for a detectable gravitational wave contribution to the microwave background anisotropy.

We propose a topological inflation model in the framework of supergravity with R invariance. This topological inflation model is not only free from the initial value problem of the inflaton field but also gives low reheating temperature which is favored in supergravity since the overproduction of graviti-nos is avoided. Furthermore, the predicted spectrum of the density fluctuations is generall...

متن کاملInflation with large supergravity corrections
It is well known that large Hubble-induced supergravity corrections to the inflaton field can ruin the flatness of the potential, thus creating a tension between slow-roll inflation and supergravity. In this paper we show that it is possible to obtain a cosmologically flat direction, embedded within the minimal supersymmetric standard model, despite very large super-Hubble corrections. As an il...
متن کاملHybrid Inflation in Supergravity
For the last 15 years cosmologists believe that something like inflation is necessary in order to construct an internally consistent cosmological theory. For more than 20 years the best hopes for the theory of all fundamental interactions are related to supersymmetry. Unfortunately it is not that simple to combine these two ideas. The main problem is that the effective potential for the inflato...
متن کاملSupersymmetric topological inflation model
We propose a topological inflation model in supergravity. In this model, the vacuum expectation value (VEV) of a scalar field takes a value much larger than the gravitational scale MG ≃ 2.4 × 10 GeV, which is large enough to cause topological inflation. On the other hand, expansions of the Kähler potential and the superpotential beyond the gravitational scale are validated by the introduction o...
