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…
Instanton Induced Open String Superpotentials and Branes at Singularities
L. E. Ibanez, A. M. Uranga
We study different aspects of the non-perturbative superpotentials induced by Euclidean E3-branes on systems of D3/D7-branes located at Abelian orbifold singularities. We discuss i…
Yukawa couplings in intersecting D-brane models
D. Cremades, L. E. Ibanez, F. Marchesano
We compute the Yukawa couplings among chiral fields in toroidal Type II compactifications with wrapping D6-branes intersecting at angles. Those models can yield realistic standard…
