Anamorphosis in hybrid inflation: How to avoid fine-tuning of initial conditions?
Sebastien Clesse
In order to generate more than 60 e-folds of accelerated expansion in original hybrid inflation, 2-fields trajectories are usually required to be initially fine-tuned in a very nar…

Fractal initial conditions and natural parameter values in hybrid inflation
Sebastien Clesse, Christophe Ringeval, Jonathan Rocher
We show that the initial field values required to produce inflation in the two fields original hybrid model, and its supergravity F-term extension, do not suffer from any fine-tuni…
