Fitting string inflation to real cosmological data: the Fibre Inflation case

Understand

In this paper we show how the string landscape can be constrained using observational data.

• We illustrate this idea by focusing on Fibre Inflation which is a promising class of string inflationary models in type IIB flux compactifications.
• We determine the values of the microscopic flux-dependent parameters which yield the best fit to the most recent cosmological datasets.
