Semi-Invariant Terms for Gauged Non-Linear Sigma-Models
M. Henneaux, A. Wilch
We determine all the terms that are gauge-invariant up to a total spacetime derivative ("semi-invariant terms") for gauged non-linear sigma models. Assuming that the isotropy subgr…
Local BRST cohomology of the gauged principal non-linear sigma model
Marc Henneaux, Andre' Wilch
The local BRST cohomology of the gauged non-linear sigma model on a group manifold is worked out for any Lie group G. We consider both, the case where the gauge field is dynamical…
Extended antifield-formalism
Friedemann Brandt, Marc Henneaux, André Wilch
The antifield formalism is extended so as to incorporate the rigid symmetries of a given theory. To that end, it is necessary to introduce global ghosts not only for the given rigi…
Global Symmetries in the Antifield-Formalism
Friedemann Brandt, Marc Henneaux, André Wilch
In this paper, two things are done. (i) First, it is shown that any global symmetry of a gauge-invariant theory can be extended to the ghosts and the antifields so as to leave inva…
