Six-dimensional (1,0) effective action of F-theory via M-theory on Calabi-Yau threefolds
Federico Bonetti, Thomas W. Grimm
The six-dimensional effective action of F-theory compactified on a singular elliptically fibred Calabi-Yau threefold is determined by using an M-theory lift. The low-energy data ar…
F-theory fluxes, Chirality and Chern-Simons theories
Thomas W. Grimm, Hirotaka Hayashi
We study the charged chiral matter spectrum of four-dimensional F-theory compactifications on elliptically fibered Calabi-Yau fourfolds by using the dual M-theory description. A ch…
Gravitational Instantons and Fluxes from M/F-theory on Calabi-Yau fourfolds
Thomas W. Grimm, Raffaele Savelli
We compactify four-dimensional N=1 gauged supergravity theories on a circle including fluxes for shift-symmetric scalars. Four-dimensional Taub-NUT gravitational instantons univers…
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 N=1 effective actions of D-branes in Type IIA and IIB orientifolds
Thomas W. Grimm, Daniel Vieira Lopes
We discuss the four-dimensional N=1 effective actions of single space-time filling Dp-branes in general Type IIA and Type IIB Calabi-Yau orientifold compactifications. The effectiv…
