Geometrical Aspects of BRST Cohomology in Augmented Superfield Formalism
In the framework of augmented superfield approach, we provide the geometrical origin and interpretation for the nilpotent (anti-)BRST charges, (anti-)co-BRST charges and a non-nilpotent bosonic charge. Together, these local and conserved charges turn out to be responsible for a clear and cogent definition of the Hodge decomposition theorem in the quantum Hilbert space of states. The above charg...

متن کاملSuperfield approach to BRST cohomology
In the framework of superfield formalism, we discuss some aspects of the cohomological features of a two (1 + 1)-dimensional free Abelian gauge theory described by a Becchi-Rouet-Stora-Tyutin (BRST) invariant Lagrangian density. We demonstrate that the conserved and nilpotent (anti-)BRSTand (anti-)co-BRST charges are the generators of translations along the Grassmannian directions of the four (...
متن کاملCohomological aspects of gauge theories: superfield formalism
Some of the key cohomological features of the two (1+1)-dimensional (2D) free Abelianand self-interacting non-Abelian gauge theories (having no interaction with matter fields) are briefly discussed first in the language of symmetry properties of the Lagrangian densities and the same issues are subsequently addressed in the framework of superfield formulation on the four (2+ 2)-dimensional super...
