Bosonic Preheating in Left-Right-Symmetric SUSY GUTs

TL;DR

This paper examines bosonic preheating in a supersymmetric hybrid inflation model with left-right symmetry, concluding that parametric boson production does not occur in this scenario.

Contribution

It provides an analysis of bosonic preheating in a specific SUSY GUT inflation model, showing the absence of parametric boson creation.

Findings

No parametric creation of bosonic particles occurs in the model.

The end of inflation involves a non-thermal phase transition that reduces gauge group rank.

The homogeneous classical field ansatz was used to analyze condensate behavior.

Abstract

We investigate the possibility of a bosonic preheating in the simplest model of supersymmetric Hybridinflation (F-term inflation), which was considered first by Dvali et al. Here the inflationary superpotential is of the O'Raifertaigh-Witten type. The end of inflation is related to a non-thermal phase transition, which in the context of left-right symmetric models lowers the rank of the gauge group. Using the homogeneous classical field ansatz for the appearing condensates, our results indicate that the parametric creation of bosonic particles does not occure in the model under consideration.
