F-Theory GUT Vacua on Compact Calabi-Yau Fourfolds
Thomas W. Grimm, Sven Krause, Timo Weigand
We present compact three-generation F-theory GUT models meeting in particular the constraints of D3-tadpole cancellation and D-term supersymmetry. To this end we explicitly constru…
Five-Brane Superpotentials and Heterotic/F-theory Duality
Thomas W. Grimm, Tae-Won Ha, Albrecht Klemm +1
Under heterotic/F-theory duality it was argued that a wide class of heterotic five-branes is mapped into the geometry of an F-theory compactification manifold. In four-dimensional…
Computing Brane and Flux Superpotentials in F-theory Compactifications
Thomas W. Grimm, Tae-Won Ha, Albrecht Klemm +1
In four-dimensional F-theory compactifications with N=1 supersymmetry the fields describing the dynamics of space-time filling 7-branes are part of the complex structure moduli spa…
Global F-theory GUTs
Ralph Blumenhagen, Thomas W. Grimm, Benjamin Jurke +1
We construct global F-theory GUT models on del Pezzo surfaces in compact Calabi-Yau fourfolds realized as complete intersections of two hypersurface constraints. The intersections…
F-theory uplifts and GUTs
Ralph Blumenhagen, Thomas W. Grimm, Benjamin Jurke +1
We study the F-theory uplift of Type IIB orientifold models on compact Calabi-Yau threefolds containing divisors which are del Pezzo surfaces. We consider two examples defined via…
