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…
The D5-brane effective action and superpotential in N=1 compactifications
Thomas W. Grimm, Tae-Won Ha, Albrecht Klemm +1
The four-dimensional effective action for D5-branes in generic compact Calabi-Yau orientifolds is computed by performing a Kaluza-Klein reduction. The N=1 Kaehler potential, the su…
Toric Resolutions of Heterotic Orbifolds
Stefan Groot Nibbelink, Tae-Won Ha, Michele Trapletti
We investigate resolutions of heterotic orbifolds using toric geometry. Our starting point is provided by the recently constructed heterotic models on explicit blowup of C^n/Z_n si…
