A Comment on Continuous Spin Representations of the Poincaré Group and Perturbative String Theory
Anamaria Font, Fernando Quevedo, Stefan Theisen
We make a simple observation that the massless continuous spin representations of the Poincaré group are not present in perturbative string theory constructions. This represents on…

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.…

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…
