Global Gluing and G-flux
Joseph Marsano, Natalia Saulina, Sakura Schafer-Nameki
Local models that capture the 7-brane physics of F-theory compactifications for supersymmetric GUTs are conveniently described in terms of an E_8 gauge theory in the presence of a…
On Seven-Brane Dependent Instanton Prefactors in F-theory
Mirjam Cvetič, Ron Donagi, James Halverson +1
We study the moduli-dependent prefactor of M5-instanton corrections to the superpotential in four-dimensional F-theory compactifications. In light of the M-theory and type IIb limi…
A Global SU(5) F-theory model with Wilson line breaking
Herb Clemens, Joseph Marsano, Tony Pantev +2
We engineer compact SU(5) Grand Unified Theories in F-theory in which GUT-breaking is achieved by a discrete Wilson line. Because the internal gauge field is flat, these models avo…
Unification and Phenomenology of F-Theory GUTs with U(1)_PQ
Matthew J. Dolan, Joseph Marsano, Sakura Schafer-Nameki
We undertake a phenomenological study of SU(5) F-theory GUT models with an additional U(1)_{PQ} symmetry. In such models, breaking SU(5) with hypercharge flux leads to the presence…
Yukawas, G-flux, and Spectral Covers from Resolved Calabi-Yau's
Joseph Marsano, Sakura Schafer-Nameki
We use the resolution procedure of Esole and Yau arXiv:1107.0733 to study Yukawa couplings, G-flux, and the emergence of spectral covers from elliptically fibered Calabi-Yau's with…
On G-flux, M5 instantons, and U(1)s in F-theory
Joseph Marsano, Natalia Saulina, Sakura Schafer-Nameki
Local aspects of singular F-theory compactifications for SUSY GUT model-building are fairly well understood in terms of Higgs bundles and their spectral data. Several global issues…
