F-theory duals of singular heterotic K3 mode
Christoph Lüdeling, Fabian Ruehle
We study F-theory duals of singular heterotic K3 models that correspond to abelian toroidal orbifolds . While our focus is on the standard embedding, we also comment on mo…
Non-Universal Anomalies in Heterotic String Constructions
Christoph Lüdeling, Fabian Ruehle, Clemens Wieck
We investigate anomalies on heterotic orbifolds and their blowups. We give a simple example of an orbifold blowup which contains anomalous U(1) symmetries that are canceled by axio…
Seven-Dimensional Super-Yang-Mills Theory in N=1 Superfields
Christoph Lüdeling
We give a gauge-covariant formulation of seven-dimensional super-Yang-Mills theory in terms of N=1 superfields. Furthermore, we show that five and seven dimensions are the only cas…
The Potential Fate of Local Model Building
Christoph Lüdeling, Hans Peter Nilles, Claudia Christine Stephan
We analyse local models at the point of E_8 in F-theory GUTs and identify exactly two models with potentially realistic properties concerning proton stability and a suitable patter…
Fixing D7 Brane Positions by F-Theory Fluxes
Andreas P. Braun, Arthur Hebecker, Christoph Ludeling +1
To do realistic model building in type IIB supergravity, it is important to understand how to fix D7-brane positions by the choice of fluxes. More generally, F-theory model buildin…
Local SU(5) Unification in 6D from the Heterotic String
C. Lüdeling
We present a six-dimensional T^2/Z_2 orbifold model which arises as an intermediate step in the compactification of the heterotic string to the MSSM. The orbifold contains two pair…
