Leptogenesis in a Realistic Supersymmetric Model of Inflation with a Low Reheat Temperature
We discuss leptogenesis in a realistic supersymmetric model of inflation with a low reheat temperature 1-10 GeV. The lepton asymmetry is generated by a decaying right handed sneutrino, which is produced after inflation during preheating. The inflationary model is based on a simple variant of the Next-to-Minimal Supersymmetric Standard model (NMSSM) which solves the μ problem, called φNMSSM, whe...
متن کاملSupersymmetric Hybrid Inflation
The non-supersymmetric and supersymmetric versions of hybrid inflation are summarized. In the latter, the necessary inclination along the inflationary trajectory is provided by radiative corrections. Supersymmetric hybrid inflation (with its extensions) is an extremely ‘natural’ inflationary scenario. The reasons are that it does not require ‘tiny’ parameters, its superpotential has the most ge...
متن کاملLeptogenesis in Supersymmetric Hybrid Inflation
The nonsupersymmetric as well as the supersymmetric hybrid inflationary model is reviewed. The scenario of baryogenesis via a primordial leptogenesis is discussed and the role of the nonperturbative electroweak sphaleron effects is analyzed in detail. A supersymmetric model based on a left-right symmetric gauge group, which ‘naturally’ leads to hybrid inflation, is presented. The μ problem is s...
متن کاملPreheating in Supersymmetric Hybrid Inflation
We study preheating in a general class of supersymmetric hybrid inflation model. Supersymmetry leads to only one coupling constant in the potential and thus only one natural frequency of oscillation for the homogeneous fields, whose classical evolution consequently differs from that of a general (non-supersymmetric) hybrid model. We emphasise the importance of mixing effects in these models whi...
متن کاملGrowth of Inflaton Perturbations and the Post-Inflation Era in Supersymmetric Hybrid Inflation Models
It has been shown that hybrid inflation may end with the formation of nontopological solitons of inflaton field. As a first step towards a fully realistic picture of the post-inflation era and reheating in supersymmetric hybrid inflation models, we study the classical scalar field equations of a supersymmetric hybrid inflation model using a semi-analytical ansatz for the spatial dependence of t...
