Stringy Instantons and Yukawa Couplings in MSSM-like Orientifold Models
L. E. Ibanez, R. Richter
Type IIA orientifold constructions with intersecting D6-branes and their IIB duals in terms of magnetized D9/D7-branes constitute one of the most promising avenues for the construc…

Yukawa Structure from U(1) Fluxes in F-theory Grand Unification
A. Font, L. E. Ibanez
In F-theory GUT constructions Yukawa couplings necessarily take place at the intersection of three matter curves. For generic geometric configurations this gives rise to problemati…
