Bottom Up Meets Heterotic Strings
Stefan Forste, Akin Wingerter
In this talk we argue that a certain class of heterotic orbifolds can be the underlying fundamental theory for recently studied field theory GUTs. In addition we demonstrate that s…
Wilson loop via AdS/CFT duality
Stefan Forste, Debashis Ghoshal, Stefan Theisen
The Wilson loop in N=4 supersymmetric Yang-Mills theory admits a dual description as a macroscopic string configuration in the adS/CFT correspondence. We discuss the correction to…
T-duality for open strings with respect to non-abelian isometries
Stefan Forste, Alexandros A. Kehagias, Stefan Schwager
We gauge the non-abelian isometries of a sigma model with boundaries. Forcing the field strength of the gauge fields to vanish renders the gauged model equivalent to the ungauged o…
Zero-branes in 2+1 dimensions
S. Forste, A. Kehagias
We discuss zero-brane solutions in three-dimensional Minkowski space-time annihilated by half of the supersymmetries. The other half of the supersymmetries which should generate th…
