Anomalous Dimensions in Deformed WZW Models on Supergroups
Constantin Candu, Vladimir Mitev, Volker Schomerus
We investigate a class of current-current, Gross-Neveu like, perturbations of WZW models in which the full left-right affine symmetry is broken to the diagonal global algebra only.…
Conformal superspace sigma-models
Vladimir Mitev, Thomas Quella, Volker Schomerus
We review recent developments in the context of two-dimensional conformally invariant sigma-models. These quantum field theories play a prominent role in the covariant superstring…
The Tetrahedron Zamolodchikov Algebra and the AdS5 x S5 S-matrix
Vladimir Mitev, Matthias Staudacher, Zengo Tsuboi
The S-matrix of the string theory is a tensor product of two centrally extended su(2|2) S-matrices, each of which is related to the R-matrix of the Hubbard model…
