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.…
The Intermediate Scale MSSM, the Higgs Mass and F-theory Unification
Luis E. Ibáñez, Fernando Marchesano, Diego Regalado +1
Even if SUSY is not present at the Electro-Weak scale, string theory suggests its presence at some scale M_{SS} below the string scale M_s to guarantee the absence of tachyons. We…
Non-Abelian discrete gauge symmetries in 4d string models
Mikel Berasaluce-Gonzalez, Pablo G. Camara, Fernando Marchesano +2
We study the realization of non-Abelian discrete gauge symmetries in 4d field theory and string theory compactifications. The underlying structure generalizes the Abelian case, and…
