A Note on Non-Flat Points in the \(SU(5)\times U(1)\) PQ F-Theory Model

Non-flat fibrations often appear in F-theory GUT models, and their interpretation is still somewhat mysterious. In this note we explore this issue in a model of particular phenomenological interest, the global \(SU(5)\times U(1)\) Peccei-Quinn F-theory model. We present evidence that co-dimension th...

Zusammenfassung:Non-flat fibrations often appear in F-theory GUT models, and their interpretation is still somewhat mysterious. In this note we explore this issue in a model of particular phenomenological interest, the global \(SU(5)\times U(1)\) Peccei-Quinn F-theory model. We present evidence that co-dimension three non-flat fibres give rise to higher order couplings in the effective four-dimensional superpotential. More specifically, in our example we find \(\mathbf{10}\, \mathbf{5}\, \mathbf{5}\, \mathbf{5}\) couplings.
