Abelian gauge symmetries and fluxed instantons in compactifications of type IIB and F-theory
Max Kerstan
We discuss the role of Abelian gauge symmetries in type IIB orientifold compactifications and their F-theory uplift. Particular emphasis is placed on U(1)s which become massive thr…
Fluxed M5-instantons in F-theory
Max Kerstan, Timo Weigand
We analyse the non-perturbative superpotential due to M5-brane instantons in F-theory compactifications on Calabi-Yau fourfolds. The M5 partition function is obtained via holomorph…
Massive Abelian Gauge Symmetries and Fluxes in F-theory
Thomas W. Grimm, Max Kerstan, Eran Palti +1
F-theory compactified on a Calabi-Yau fourfold naturally describes non-Abelian gauge symmetries through the singularity structure of the elliptic fibration. In contrast Abelian sym…
On Fluxed Instantons and Moduli Stabilisation in IIB Orientifolds and F-theory
Thomas W. Grimm, Max Kerstan, Eran Palti +1
We study the superpotential induced by Euclidean D3-brane instantons carrying instanton flux, with special emphasis on its significance for the stabilisation of Kahler moduli and N…
The effective action of D6-branes in N=1 type IIA orientifolds
Max Kerstan, Timo Weigand
We use a Kaluza-Klein reduction to compute the low-energy effective action for the massless modes of a spacetime-filling D6-brane wrapped on a special Lagrangian 3-cycle of a type…
