On Discrete Symmetries and Torsion Homology in F-Theory
Christoph Mayrhofer, Eran Palti, Oskar Till +1
We study the relation between discrete gauge symmetries in F-theory compactifications and torsion homology on the associated Calabi-Yau manifold. Focusing on the simplest example o…
Discrete Gauge Symmetries by Higgsing in four-dimensional F-Theory Compactifications
Christoph Mayrhofer, Eran Palti, Oskar Till +1
We study F-Theory compactifications to four dimensions that exhibit discrete gauge symmetries. Geometrically these arise by deforming elliptic fibrations with two sections to a gen…
Towards the Standard Model in F-theory
Ling Lin, Timo Weigand
This article explores possible embeddings of the Standard Model gauge group and its matter representations into F-theory. To this end we construct elliptic fibrations with gauge gr…
Mordell-Weil Torsion and the Global Structure of Gauge Groups in F-theory
Christoph Mayrhofer, David R. Morrison, Oskar Till +1
We study the global structure of the gauge group of F-theory compactified on an elliptic fibration . The global properties of are encoded in the torsion subgroup of the…
D7-Brane Moduli Space in Axion Monodromy and Fluxbrane Inflation
Maximilian Arends, Arthur Hebecker, Konrad Heimpel +5
We analyze the quantum-corrected moduli space of D7-brane position moduli with special emphasis on inflationary model building. D7-brane deformation moduli are key players in two r…
Towards large r from [p,q]-inflation
Eran Palti, Timo Weigand
The recent discovery of B-mode polarizations in the CMB by the BICEP2 collaboration motivates the study of large-field inflation models which can naturally lead to significant tens…
