Complete Intersection Fibers in F-Theory
Volker Braun, Thomas W. Grimm, Jan Keitel
Global F-theory compactifications whose fibers are realized as complete intersections form a richer set of models than just hypersurfaces. The detailed study of the physics associa…
Yukawas and discrete symmetries in F-theory compactifications without section
Iñaki García-Etxebarria, Thomas W. Grimm, Jan Keitel
In the case of F-theory compactifications on genus-one fibrations without section there are naturally appearing discrete symmetries, which we argue to be associated to geometricall…
Physics of F-theory compactifications without section
Lara B. Anderson, Iñaki García-Etxebarria, Thomas W. Grimm +1
We study the physics of F-theory compactifications on genus-one fibrations without section by using an M-theory dual description. The five-dimensional action obtained by considerin…
From M-theory higher curvature terms to α' corrections in F-theory
Thomas W. Grimm, Jan Keitel, Raffaele Savelli +1
We perform a Kaluza-Klein reduction of eleven-dimensional supergravity on a Calabi-Yau fourfold including terms quartic and cubic in the Riemann curvature and determine the induced…
Geometric Engineering in Toric F-Theory and GUTs with U(1) Gauge Factors
Volker Braun, Thomas W. Grimm, Jan Keitel
An algorithm to systematically construct all Calabi-Yau elliptic fibrations realized as hypersurfaces in a toric ambient space for a given base and gauge group is described. This g…
Effective action of 6D F-Theory with U(1) factors: Rational sections make Chern-Simons terms jump
Thomas W. Grimm, Andreas Kapfer, Jan Keitel
We derive the six-dimensional (1,0) effective action arising from F-theory on an elliptically fibered Calabi-Yau threefold with multiple sections. The considered theories admit bot…
