Boundary Spectra in Superspace Sigma-Models
Thomas Quella, Volker Schomerus, Thomas Creutzig
In this note we compute exact boundary spectra for D-instantons in sigma-models on the supergroup PSL(2|2). Our results are obtained through an explicit summation of the perturbati…
Structure constants of the OSP(1|2) WZNW model
Yasuaki Hikida, Volker Schomerus
We propose exact formulas for the 2- and 3-point functions of the WZNW model on the non-compact supergroup OSP(1|2). Using the path integral approach that was recently developed in…
Branes in the GL(1|1) WZNW-Model
Thomas Creutzig, Thomas Quella, Volker Schomerus
We initiate a systematic study of boundary conditions in conformal field theories with target space supersymmetry. The WZNW model on GL(1|1) is used as a prototypical example for w…
Strings for Quantumchromodynamics
Volker Schomerus
During the last ten years, intriguing dualities between gauge and string theory have been found and explored. They provide a novel window on strongly coupled gauge physics, includi…
Free fermion resolution of supergroup WZNW models
Thomas Quella, Volker Schomerus
Extending our earlier work on PSL(2|2), we explain how to reduce the solution of WZNW models on general type I supergroups to those defined on the bosonic subgroup. The new analysi…
H^+_3 WZNW model from Liouville field theory
Yasuaki Hikida, Volker Schomerus
There exists an intriguing relation between genus zero correlation functions in the H^+_3 WZNW model and in Liouville field theory. We provide a path integral derivation of the cor…
