High U(1) charges in type IIB models and their F-theory lift
Francesco Mattia Cianci, Damian Kaloni Mayorga Pena, Roberto Valandro
We construct models with U(1) gauge group and matter with charges up to 6, in the context of type IIB compactifications. We show explicitly that models with charges up to 4 can be…

Weak coupling limit of F-theory models with MSSM spectrum and massless U(1)'s
Damian Kaloni Mayorga Pena, Roberto Valandro
We consider the Sen limit of several global F-theory compactifications, some of which exhibit an MSSM-like spectrum. We show that these indeed have a consistent limit where they ca…
