On the evaluation of the evolution operator Z_Reg(R_2,R_1) in the Diakonov-Petrov approach to the Wilson loop

M. Faber, A. N. Ivanov, N. I. Troitskaya

We evaluate the evolution operator Z_Reg(R_2,R_1) introduced by Diakonov and Petrov for the definition of the Wilson loop in terms of a path integral over gauge degrees of freedom.…

General Two-Dimensional Supergravity from Poisson Superalgebras

M. Ertl, W. Kummer, T. Strobl

We provide the geometric actions for most general N=1 supergravity in two spacetime dimensions. Our construction implies an extension to arbitrary N. This provides a supersymmetriz…

RR charges of D2-branes in group manifold and Hanany-Witten effect

Takahiro Kubota, Jian-Ge Zhou

By exploiting the correspondence between the Cardy boundary state in SU(2) group manifold and the BPS D3-brane configuration in the full asymptotically flat geometry of NS5-branes,…

Center vortex model for the infrared sector of Yang-Mills theory

M. Engelhardt, M. Faber, H. Reinhardt

A model for the infrared sector of SU(2) Yang-Mills theory, based on magnetic vortices represented by (closed) random surfaces, is presented. The random surfaces, governed by an ac…

The Superfield Formalism Applied to the Noncommutative Wess-Zumino Model

A. A. Bichl, J. M. Grimstrup, H. Grosse +3

We introduce the notion of superoperators on noncommutative R^4 and re-investigate in the framework of superfields the noncommutative Wess-Zumino model as a quantum field theory. I…

Actions and symmetries of NSR superstrings and D-strings

Friedemann Brandt, Alexander Kling, Maximilian Kreuzer

We present all NSR superstring and super-D-string actions invariant under a set of prescribed gauge transformations, and characterize completely their global symmetries. In particu…
