Non-perturbative effects and Yukawa hierarchies in F-theory SU(5) Unification
Anamaría Font, Luis E. Ibáñez, Fernando Marchesano +1
Local SU(5) F-theory models lead naturally to Yukawa couplings for the third generation of quarks and leptons, but inducing Yukawas for the lighter generations has proven elusive.…
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…
Phenomenology of a Fluxed MSSM
B. C. Allanach, A. Brignole, L. E. Ibanez
We analyze the phenomenology of a set of minimal supersymmetric standard model (MSSM) soft terms inspired by flux-induced supersymmetry (SUSY)-breaking in Type IIB string orientifo…
Computing Yukawa Couplings from Magnetized Extra Dimensions
D. Cremades, L. E. Ibanez, F. Marchesano
We compute Yukawa couplings involving chiral matter fields in toroidal compactifications of higher dimensional super-Yang-Mills theory with magnetic fluxes. Specifically we focus o…
