General inflaton potentials in supergravity
Renata Kallosh, Andrei Linde, Tomas Rube
TL;DR
This paper presents a method to construct supergravity models with customizable inflaton potentials, ensuring stability of scalar fields during inflation through specific Kähler potential choices.
Contribution
It introduces a systematic approach to design supergravity inflation models with arbitrary potentials and stable scalar field configurations.
Findings
All scalar fields can be stabilized at the inflationary trajectory.
The inflaton potential V(φ) can be arbitrarily chosen within the model.
Stability is achieved by proper selection of the Kähler potential.
Abstract
We describe a way to construct supergravity models with an arbitrary inflaton potential V ({\phi}) and show that all other scalar fields in this class of models can be stabilized at the inflationary trajectory by a proper choice of the K\"ahler potential.
