Retrofitting Models of Inflation

TL;DR

This paper applies the retrofitting method to supersymmetric inflation models, dynamically generating a naturally small inflation scale and demonstrating its versatility on F-term and D-term inflation examples.

Contribution

It introduces a general retrofitting procedure to generate small inflation scales in existing supersymmetric inflation models.

Findings

Successfully retrofitted F-term inflation model with small inflation scale

Successfully retrofitted D-term inflation model with small inflation scale

Demonstrated the method's applicability to different supersymmetric inflation models

Abstract

I use the method of retrofitting, developed by Dine, Feng and Silverstein, to generate the scale of inflation dynamically, allowing it to be naturally small. This is a general procedure that may be performed on existing models of supersymmetric inflation. I illustrate this idea on two such models, one an example of F-term inflation and the other an example of D-term inflation.
