Gauge coupling unification in F-theory grand unified theories.
TLDR
It is shown how F-theory can evade gauge symmetry breaking via nontrivial hypercharge flux in a natural way and spoil the celebrated one-loop gauge coupling unification.

TOWARD REALISTIC INTERSECTING D-BRANE MODELS
▪ Abstract We provide a pedagogical introduction to a recently studied class of phenomenologically interesting string models known as Intersecting D-Brane Models. The gauge fields of the Standard
Moduli Stabilisation versus Chirality for MSSM like Type IIB Orientifolds
We investigate the general question of implementing a chiral MSSM like D-brane sector in Type IIB orientifold models with complete moduli stabilisation via F-terms induced by fluxes and space-time
