Model Building with F-Theory

TL;DR

This paper explores F-theory compactifications for model building, demonstrating how they can naturally incorporate gauge coupling unification and matching heterotic duals, advancing the understanding of string phenomenology.

Contribution

It extends model building frameworks by detailing F-theory compactifications with G-flux, providing methods to derive spectra and couplings, and establishing duality with heterotic models.

Findings

F-theory models can incorporate gauge unification more naturally.

Matching results between F-theory and heterotic computations are demonstrated.

A method to derive chiral spectra and Yukawa couplings in F-theory is provided.

Abstract

Despite much recent progress in model building with D-branes, it has been problematic to find a completely convincing explanation of gauge coupling unification. We extend the class of models by considering F-theory compactifications, which may incorporate unification more naturally. We explain how to derive the charged chiral spectrum and Yukawa couplings in N=1 compactifications of F-theory with G-flux. In a class of models which admit perturbative heterotic duals, we show that the F-theory and heterotic computations match.
